A bystander captured the chaos at Dignity Health Sports Park in Los Angeles following the Galaxy's 1-1 draw with LAFC ... and you can see in the footage, multiple people threw and landed huge punches and kicks.

It's unclear what set off the altercation ... but even with security guards and what appears to be police officers present -- fans still tried to beat the hell out of each other.

In the two-minute clip, you can see several people were punched in the face, while others were kicked hard on the ground.

According to witnesses, multiple people suffered injuries in the fracas. Meanwhile, it's unclear if any arrests were made -- we've reached out to law enforcement, but so far, no word back yet.

We've also reached out to Galaxy for a comment, but no word back there yet either.

MMA's Justin Thornton Dead At 38 Weeks After Violent KO Loss

Published

Tragic news ... MMA fighter, Justin Thornton, has died at 38 years old, just weeks after he was violently knocked out in an August fight.

Thornton was seriously hurt after Dillon Cleckler KO'ed him during a Bare Knuckle Fighting Championship event on Aug. 20.

The scene in the ring was very scary ... after taking multiple punches to the face, Thornton crashed headfirst into the mat and didn't move for several minutes.

BKFC officials confirmed Monday that Thornton -- who had reportedly been battling serious injuries from the fight -- has died.

It's unclear, however, if the KO had anything to do with the passing, as a cause of death has yet to be revealed.

"This morning we were very saddened to be notified of the passing of one of our fighters, Justin Thornton, who competed at BKFC 20 on August 20, 2021," BKFC president Dave Feldman said in a statement.

"We join the rest of the combat sports community in sending our deepest condolences to his family and loved ones."

Thornton had been professionally fighting for over a decade ... compiling a 6-18 record.

RIP

UFC's Kevin Holland I Stopped An Alleged Carjacker Chased, Held Him For Cops

JUMPIN' IN FOR JUSTICE

Who says Kevin Holland can't wrestle?!

The MMA star thwarted an alleged carjacking Monday morning -- just 2 days after the wild ending at UFC Fight Night -- tracking down the accused thief in his car, and holding him down until police in Saginaw, TX arrived on the scene.

TMZ Sports talked to the 28-year-old fighter ... and he gave us a play-by-play of the crazy scene.

Holland details how he immediately sprang into action after being flagged down by the guy whose car was allegedly taken, and found himself in the middle of a wild chase.

It's a crazy story made even crazier by the timing ... Holland was just involved in a controversial fight Saturday night against Kyle Daukaus.

Less than 3 minutes into the fight, Holland and Daukaus accidentally clashed heads, briefly knocking Kevin out.

He quickly regained consciousness, but the brief moment Kevin was out allowed Kyle to get his neck, ultimately choking KH out, forcing him to tap.

Referee Dan Miragliotta consulted with fellow ref Herb Dean, the Nevada Athletic Commission, and UFC officials before deciding to declare the fight a no contest.

Despite the wild past few days, Holland is in good spirits, and gives a hysterical breakdown of the situation.

Somebody get this guy a medal!

Claressa Shields On 2nd MMA Opponent: 'I'm Tryin' To Break Her Jaw'

Published | Updated

Claressa Shields says a knockout isn't enough for her 2nd MMA fight ... she's trying to BREAK BONES, telling TMZ Sports she's been putting in a ridiculous amount of work in the gym, and is ready to go!

26-year-old Shields -- regarded by many as the greatest female boxer in the world -- is set to return to the cage for her 2nd MMA fight on October 27 at a big PFL event in Hollywood, FL ... taking on 21-year-old Abigail Montes.

"She a decorated amateur kickboxer. Even though she only has 2 fights in MMA, she's been kickboxing for I don't know how many years in Mexico," Claressa says.

"She comes forward with a lot of punches, so, we're definitely gonna see a very, very entertaining fight and I know I'm gonna handle business and I'm trying to break Abigail's jaw, for sure."

😲😲😲😲😲😲

Shields flashed potential in her first MMA fight against Brittney Elkin in June ... winning via 3rd round TKO. However, she faced adversity ... repeatedly being taken down by the more experienced MMA fighter.

We asked Claressa how much time she's spent defending the takedowns ... and lets just say she's really been bustin' her ass.

"Every day. Every day. That's something we work on every single day, and I've gotten very good at it. Very good."

But, Shields isn't just working on her defense ... she tells us she's also drilled her takedown offense AND kick game.

"If I can stop the takedown, a lot of people's in trouble. If I can go for the takedown, people are in trouble. When I start adding those kicks to my punches, people are in trouble."

Big trouble.

Lamar Odom Beats J Lo's Ex In Celeb Boxing ... Benzino Demands Next!!

Published | Updated

Lamar Odom didn't get the knockout he predicted, but the NBA champ looked good in the boxing ring Saturday night, beating up Jennifer Lopez's ex-husband, Ojani Noa ... before being called out by Benzino!

41-year-old Odom beat 47-year-old Noa, who was hitched to Lopez from 1997-1998, by decision in a 3-round exhibition Celebrity Boxing fight in Miami, FL.

6'10" Lamar had a 9-inch height advantage over J Lo's 6'1" ex-hubby ... and wisely used his length to stay on the outside and jab Ojani, keeping him at a distance where Noa couldn't get close enough to hit Odom.

Even though he didn't get the stoppage, Lamar looked considerably better than in his first fight in June against Aaron Carter.

Odom knocked out the pop star in the second round.

Noa, who is in good physical shape, clearly presented a tougher challenge.

But, 56-year-old Benzino, who was calling the fight ringside for FITE, clearly didn't think Lamar looked very good.

"I wasn't impressed with that fight," Benzino yelled in the ring following the bout, "I want a shot at the champ!"

The champ ... at least unofficially is Lamar Odom.

And, there's a good chance this fight will go down. Celebrity Boxing tells TMZ Sports the hip-hop star is under contract to fight in March.

BUILDIN' THE BUSINESS

Of course, we broke the story on Saturday ... Odom recently became a part-owner of Celeb Boxing and told us he was willing to continue fighting.

Lamar Odom vs. Benzino would make for an interesting fight ... if CB can hammer out all the details.

Stay tuned!

BOOSIE BREAKS IT UP
UPDATE

9:25 AM PT -- TMZ has learned that the Atlanta Police Department did respond to a vandalism call at 12:41 AM today.

UPDATE

APD tells us Boosie and several of his associates dashed onto the stage during the event and started damaging items belonging to their production company. The group also allegedly destroyed property owned by the arena.

UPDATE

No injuries were reported. Police are continuing with the investigation.

Boosie Badazz performed for all of 2 minutes Friday night when a fight broke out on stage ... and it got so insane promoters pulled the plug on the entire concert.

It went down in Atlanta at the "Legendz of the Streetz" concert with an all-star ensemble which included 2 Chainz, Rick Ross, Jeezy, Lil Kim, Gucci Mane, and Fabolous.

A couple minutes into Boosie's set, someone came down from the DJ booth and started swinging at another guy on stage. Unclear what triggered his anger.

Check out the video ... Boosie, in white pants and a pink jacket, is standing at the front of the stage, and when he eyes the fight he beelines it for the action and jumps right in.

You see a security guard guiding Boosie off stage while the fighting escalates ... speakers are knocked over and basically, they all start trashing the joint.

That was enough for the venue ... the house lights went up and the show was over.

There were no injuries to speak of and cops weren't called.

Jake Paul I'll Turn Amanda Serrano Into A Superstar ... Billboards, Sponsorships, Big Fights

Published | Updated
093021_jake_paul_amanda_serrano_kal OCTOBER 2021
QUALITY OVER QUANTITY

Jake Paul turned himself into one of the biggest stars in combat sports, and now The Problem Child tells TMZ Sports he's gunning to recreate the formula and turn Amanda Serrano, arguably the greatest female fighter in the world, into a giant star.

"Amanda’s the number one pound-for-pound female boxer and greatest Hispanic female athlete of all time, and she hasn’t been treated fairly in her career. She’s a superstar and she needs that extra backing or help." Paul, joined virtually by Serrano, told us.

Paul just signed Serrano to his promotion company, Most Valuable Promotions (MVP) ... and says the plan is to turn Serrano, the unified featherweight champ (41-1-1), into a famous, big money fighter.

"Slowly but surely, we’re knocking that wall down and she will become a superstar with our guidance. She’s already a superstar but just taking it to the next level," Paul says.

"She needs to be on billboards. She needs to be sponsored by the biggest companies in the world. She embodies so much and is so powerful and we’re just gonna help her out."

The question is ... why does Amanda trust her career with the most polarizing figure in combat sports?

"I’ve seen him and what they’ve done in the last two years. How he’s made his name boxing, coming from YouTube, an influencer and I'm just excited to see what he’s done with himself and I'm excited to see what he can do for me," Serrano told us.

"I’ve been in this sport so long and never got the fair shake of it and I’m excited to have him as part of my team to help me with the other end of it."

We asked Jake if he plans on signing other fighters ... and building out his promotion company.

Waiting for your permission to load the Instagram Media.

"That’s the idea with Most Valuable Promotions, but we’re not in a rush. If we end up only signing one, two, three fighters, then so be it. It’s about quality over quantity and right now our focus is fully on Amanda."

Sleep with one eye open, Eddie Hearn and Bob Arum.

Lamar Odom Buys Into Celebrity Boxing ... I'm A Partial Owner Now

Published | Updated
100121-lamar-odom-kal
BUILDIN' THE BUSINESS

Lamar Odom loved Celebrity Boxing so much ... he literally bought the company.

Well, some of it, at least ... 'cause when we asked the NBA champion if he planned on continuing to fight, that's when he dropped the news, telling TMZ Sports he's now a partial owner of the organization.

"I'm a part owner in Celebrity Boxing, so if I gotta keep fighting to keep building the brand, I don't see no problem with that, being a businessman," Odom says.

41-year-old Odom is boxing Ojani Noa, Jennifer Lopez's ex-husband, Saturday night in Miami.

It's not LO's first time in the ring ... back in June, the ex-NBA star knocked out Aaron Carter in the 2nd round of their boxing match.

Lamar was originally supposed to fight former heavyweight champ, 54-year-old Riddick Bowe ... but the fight was scrapped after there were concerns about the boxing legend's ability to protect himself in the ring.

So, 47-year-old Noa -- a gym rat -- stepped up and took the fight.

Odom believes his 2nd fight, although he has more experience, will be tougher than when he faced the former pop star ... but, not that much harder.

"Hopefully, I can just put him out in the 3rd."

Mike Tyson 'Hell Yeah' I'd Fight Logan Paul ... Envisions $100 Mil Payday

Published | Updated

First, Floyd Mayweather ... next, Mike Tyson??

That very well could be a reality for Logan Paul ... 'cause Iron Mike says he's now down to box the YouTube star -- claiming the fight could earn the two a fortune!!

Tyson revealed on his latest episode of "Hotboxin' With Mike Tyson" that he'd have zero issues stepping into the ring with either Logan or Jake Paul ... adding the scrap could net a $100 million payday.

"Hell yeah," Tyson said when rapper Freddie Gibbs asked if he'd box the two YouTube stars. "That would be a lot of money."

Tyson seems to think boxing Logan would make more sense than fighting Jake ... considering the elder Paul bro is a bit heavier.

As for if Logan would do it ... Tyson certainly thinks so -- telling Gibbs, "For $100 million bucks, they'd do anything. They don't care about getting beat up."

Tyson -- who's coming off a great performance against Roy Jones Jr. -- had previously told us he was eyeing Lennox Lewis for his next bout.

But, if Logan's down ... seems Tyson would have no problem moving on to that tilt.

Ya listenin', Logan??

Aspen Ladd Blames 'Miserable' Weight Cut On Period ... Fight Off

Published
UPDATE

12:47 PM PT -- Aspen confirms the fight is off ... but says the UFC didn't scrap the fight -- she claims it was Chiasson who backed out.

UPDATE

"Straight up started my period 2 days back and made this cut absolutely miserable," Ladd said on Instagram minutes ago.

UPDATE

"Did the best I could, hit 137, the scale situation was a mess because the last thing I wanted was to bleed in front of the media."

UPDATE

12:46 PM PT -- Ladd says it was "absolutely" Chiasson's right to not go through with the fight ... but understands there will be haters regardless.

The UFC has stepped in and called off the Aspen Ladd vs. Macy Chiasson fight slated for UFC Vegas 38 on Saturday ... after Ladd appeared dangerously frail during the weigh-in.

The scene was scary -- Ladd was visibly shaking and barely able to hold her arms up as she stepped on the scale ... with many concerned about her health as she tried to make weight at 135 pounds.

Ladd eventually weighed in at 137 -- 2 pounds over the bantamweight limit -- but there was no way Dana White's org. was going to let Ladd take the Octagon for a catchweight bout ... with the fight being scrapped just moments ago.

This is not the first time Ladd has had a grueling experience at a weigh-in -- in 2019, she also showed serious signs of struggling as she made weight for UFC Fight Night 155.

But Ladd did not look her usual self in the Octagon after, losing in a TKO in less than a minute against Germaine de Randamie.

Here's hoping Ladd can recover and get back on the right track.

G-EAZY'S DAY IN COURT

G-Eazy's gotta be careful the next time he goes out for a drink in NYC -- he's been ordered to keep away from the guys with whom he allegedly brawled with in a nightclub.

The rapper just left a Big Apple courtroom where he was charged with misdemeanor assault for allegedly punching a guy in the head at the Boom Boom Room at the Standard Hotel.

The judge ordered G-Eazy to steer clear of his alleged victim, plus the man who claims G's entourage smashed a glass bottle over his head in last month's altercation.

G-Eazy was released without bail, and was in no mood to talk when we got him leaving the courthouse.

TMZ broke the story ... G-Eazy was arrested in September after he and his crew allegedly got violent with another group of guys in a bar.

He's scheduled to be back in court next month. Until then, he'll need to tread lightly on the bar scene.

DETAILED DESCRIPTION

Gabby Petito told a Utah police officer that Brian Laundrie hit her during their August 12 dispute in Moab, but then quickly walked it back and said he actually grabbed her face after she hit him first.

New bodycam footage from a second police officer sheds new light on the incident, in which Gabby and Brian were separated after cops were called because they were seen fighting in public.

The new video is far more audible than the one released earlier ... and this one provides a much more detailed account by Gabby ... the key moments can be clearly heard.

The officer notices various marks on Gabby -- on her face and her arm, and gently asks what happened.

Listen for yourself -- when the cop asks Gabby bluntly if Brian hit her, she says "I guess, yeah, but I hit him first." She then explains he grabbed her face and demonstrates how his fingernail may have scratched her cheek.

100121_gabby_petito_kal 8/12/21
WORKING WITH GABBY

Gabby says Brian did not punch or hit her in the face, though.

As we reported ... two 911 callers did report that Brian struck Gabby's face. However, in the initial police report released a couple weeks ago ... police wrote that both Gabby and Brian claimed that she began slapping him first, and he grabbed her face and pushed her away.

100121_gabby_petito_officers_kal
DEADLY DECISION

There's another eerie video ... where 2 cops involved in the incident try to determine if it rises to the level of domestic assault, but ultimately seem to decide on the spot that it doesn't.

One of the officers even implies that Brian may be the one at risk of becoming a "battered man" ... but he doesn't think that's the case.

As you know ... Gabby was found dead at a Wyoming state park, and Brian is the main person of interest in her death.

UPDATE
UPDATE

The man, 48-year-old Angelo Zappacosta, is accused of shoving the other man in the video in the chest and taking a swing at him ... though it didn't connect. According to the alleged victim ... Zappacosta was upset over him reportedly being on his property days earlier handing out wanted posters for Laundrie.

Tensions are boiling over on Brian Laundrie's block, a fight just broke out right in front of his Florida home involving one of the family's neighbors.

Ya gotta see the video ... the neighbor, in a red shirt, starts screaming at a couple of protestors who have set up camp outside the Laundrie family home ... accusing the couple of stepping on his property.

The man sounds like he's had enough of the protestors on his street, threatening to open a can of whoop-ass if the protestors step foot on his property ... something he's already accused them of doing before.

The showdown is super intense ... and it gives a sense of the tensions building on Brian's block.

As you know ... there's a manhunt for Brian, and the FBI has already searched the house.

The altercation outside Brian's home comes on the heels of a makeshift floral Gabby Petito memorial on the front lawn getting tossed in the garbage.

Bottom line ... Brian's neighborhood is on edge.

Jon Jones Swears Off Alcohol ... After Vegas Arrest

Published | Updated
UPDATE

6:38 PM PT -- Jon Jones is promising to make some serious changes in his life following his arrest ... and it's starting with swearing off alcohol.

UPDATE

Jones posted a video to his Instagram story moments ago ... showing the UFC superstar working out and promising to come back better than ever.

UPDATE

The fighter captioned the post with several statements ... including his decision to step away from booze for good.

UPDATE

"I have way too much trauma to consume alcohol, my brain simply can't handle it anymore," Jones said. "Now is the time to work harder than ever."

UPDATE

Jones also says he plans to "turn this nightmare into the best thing to ever happen in my life" and "get right back on my horse."

Jon Jones allegedly pulled his fiancee's hair and then headbutted a police car, leaving a dent in the hood and chipping paint, during his Las Vegas arrest early Friday morning, TMZ Sports has learned.

According to a Vegas Metro PD arrest report, cops were called to Caesars Palace around 5:08 AM for a "domestic disturbance" in a hotel room ... involving a white female who was "bleeding from her nose/mouth" and a "black male adult who is a professional MMA fighter."

When police arrived, they spotted Jon walking near the hotel, where they stopped and detained him.

Cops say 34-year-old Jones became "irate and smashed his head onto the front hood of the LVMPD patrol vehicle," leaving a medium-sized dent, as well as chips in the paint.

While handcuffed, police say Jones experienced a wide range of emotions. At one point, cops say he threatened to sue the department for handcuffing him on the biggest night of his life.

FYI, Jones' 2013 fight with Alexander Gustaffson was inducted in the UFC's Hall of Fame only hours before his arrest.

The officers also claim Jon joked about wanting to fight all the cops, to see if he could take them all on at the same time.

Police say they then interviewed the alleged victim, Jon's fiancée, Jessie, and the mother of his 3 kids, who claimed she was asleep when Jones came back to their room after a night out in Vegas with his friends.

Jessie told police "Jon came back and was not very happy." When they asked her if things turned physical, she replied "Umm not too physical but a little bit yeah."

When cops asked what she meant, Jessie said, "he touch the back of my head and pulled my hair a little bit but he did not hit me or anything."

However, cops said they noticed blood on her lip, which was also swollen. Jessie told cops it was because they were dry. Police also say they saw blood on her sweatshirt.

Cops checked Jon and Jessie's hotel room, and say they saw blood on the bedsheets.

When detectives were leaving the scene, they note Jessie was concerned about when Jon would be released from county jail.

As for who called the police, Jessie went down to a security booth to ask for an additional room key around 4:30 AM. A security guard said she saw blood on her person, and asked Jessie if she was okay. The guard claimed Jessie then began to cry and said she was scared to return to her room.

The guard then claims Jessie and Jon's youngest child said "can you call the cops?"

Jones -- who told police he never got physical his fiancée -- was ultimately arrested for misdemeanor domestic battery and felony tampering with a vehicle.

Jon has a court date scheduled next month.

Alexander Volkanovski I Was Never Tapping ... But Was Moments Away From Unconsciousness

Published | Updated

Alexander Volkanovski says he was only moments away from losing consciousness when Brian Ortega had him in a guillotine at UFC 266, telling TMZ Sports there were 2 options -- get out or go out.

... 'cause he was NEVER gonna tap.

We talked to the UFC featherweight champ following his dominating win over Brian Ortega ... and although AV won via unanimous decision, things got dicey in the 3rd round when Ortega had Volkanovski in a choke so tight that Alex's surroundings literally started to change colors.

"It was getting close where I couldn't breathe," Volkanovski says.

"It was definitely close. But, again, I was never going to stop trying to get out of it and I was never going to tap."

Then, almost out of a movie scene, Volkanovski says he imagined going home to his family without his championship belt.

"I remember I had like a moment, it was weird 'cause I was literally thinking of my family, and I was like man, I might not be taking this belt home to my family. You can't let it end like this."

"I literally had a moment like that, like s*** you see in the movies."

Bottom line, if you thought Alex wasn't in trouble, you're wrong ... 'cause "mate, it was deep. It was deep."

We also talked to Alex about the controversy in between the 3rd and 4th rounds ... when Volkanovski believes Ortega was incorrectly provided precious time to recover, while Herb Dean and the doctor attempted to determine if T-City was fit to continue fighting.

AV says the fight should've been stopped right there.

"[Brian] was stumbling when they were asking him to move. They definitely should've ... I didn't even realize his corner picked him up and put him on the stool, which you're not allowed to do. You hear things like that and you're like, 'I'm surprised that they didn't stop it.' But, all good."

Matter of fact, Alex says he's sorta happy the fight wasn't stopped ... because fans got a helluva 5-round fight.

So, what's next for the featherweight champ? He's got options.

092821_alexander_volkanovski_kal_2
SOUNDS LIKE A GOOD TIME

Conor McGregor tweeted about Volkanovski following the fight, writing ... "Not a bad fight. Congrats shartsy"

Is Alex interested in a fight at 155 pounds with The Notorious? We asked him.

"Of course you'd want that."

In fact, Alex says because Max Holloway (#1) and Yair Rodriguez (#3) aren't fighting until the end of the year (the winner likely being his next opponent in the featherweight division) ... he's got some time to kill.

And, a big money fight with McGregor, in AV's words, "sounds like a good time."

(Worth noting, Conor broke his leg only 80 days ago, and won't be ready to fight until sometime next year.)

Then there's Henry Cejudo ... who just told us he wanted to fight Alex at 145 lbs., and become the first UFC fighter to hold belts in 3 divisions.

092721_henry_cejudo_kal_1
"STICK TO THE GAME PLAN"

Unfortunately for the man on a quest to become Quadruple C, Alex says he isn't interested.

"Nah, there's no point even wasting energy with it."

"Obviously, [Henry's] gonna keep chirping and keep carrying on like he does whenever a flyweight, or a bantamweight or a featherweight, if there's ever a fight, he's got something to say, but I'll let him keep chirping in the background."

Kansas City Chiefs Fan Knocked Out In Wild Brawl ... At Arrowhead Stadium

Published | Updated

A Kansas City Chiefs fan was pummeled so hard during a wild brawl in the stands at Arrowhead Stadium on Sunday -- he appeared to be knocked out cold.

The violence all went down at some point during the Chiefs' game against the Chargers ... when K.C. fans got into a heated altercation.

In footage of the incident, filmed by bystanders, you can see the melee was all kicked off after one fan threw a huge haymaker amid a verbal argument.

That's when all hell broke loose -- 'cause several other fans ran into the area, throwing wild punches.

In the clip, you can see things got so bad ... a man appeared to be punched unconscious, with his limp body sprawled out over a row of seats.

Unclear if anybody suffered any serious injuries in the fight, or if any arrests were made. We've reached out to cops, but so far, no word back yet.

Of course, the brawl is just the latest in a long line of scraps at NFL stadiums this season ... remember, there were at least two huge altercations at SoFi Stadium earlier this month and one giant fracas at a Cleveland Browns game as well.
