Nurse!

"I said, 'Wait a second, where the f*** is his finger?' They were all like, 'I don't know.'"

That's how one witness described seeing an MMA fighter LOSE A FINGER mid-match Thursday night ... and, yeah, the injury was just as horrific as it sounds.

During Khetag Pliev's bout with Devin Goodale at Cage Fury Fighting Championship in Philadelphia, officials had to stop the fight when they noticed Pliev was missing a freakin' finger.

The images were INSANE ... video of 37-year-old Pliev in his corner showed the ring finger on his left hand had been completely severed at some point during his match.

The problem? For several minutes, nobody could find the missing digit!

Event promoter Rob Haydak told ESPN there was a mad scramble to try to help locate it ... with the PA announcer even having to ask fans in the 2300 Arena stands if they'd seen it!

"It was a surreal moment," Haydak said.

Eventually, Pliev's finger was found tucked away in his glove -- where it had been the entire time -- but, here's the crazy part ... Pliev did NOT immediately go to the hospital to have it reattached!!!

Haydak says Pliev actually begged to continue the match ... and even though officials wouldn't let him, he still stayed in the ring for the post-fight announcement, where Goodale was rewarded with a TKO decision.

"It was crazy," Haydak said. "He didn't even flinch. He was getting ready to do the [official] decision and I was like, 'Uh, guys, get him out of the cage and go put his finger back on.'"

Pliev -- who did ultimately go to the emergency room to have his finger attached -- says he believes he suffered the injury after Goodale had grabbed at his glove early in the fight.

"In the second round, he caught my glove with one hand and held it," Pliev said. "I felt my finger snapped. He kept pulling my glove and my finger snapped. We kept fighting."

"When the second round was finished, I see my [bone] was out in the open. I wanted to keep fighting, because I felt like I had this guy. But, the doctor saw that and stopped the fight. "

Pliev -- a wrestler who competed for Canada in the 2012 Olympics -- came into the fight with a 5-1 record. He said he plans on appealing Thursday night's fight result.

The G.O.A.T.'s knee is healing up just fine ... Buccaneers GM Jason Licht says Tom Brady's recovering "very well" from offseason surgery.

The 43-year-old Tampa Bay QB had to go under the knife shortly after winning his 7th Super Bowl ... with Licht saying TB12 needed a "minor surgical procedure" to clean up some things in his leg.

But, Licht says there are no worries as of now that Brady might have to miss regular-season action in 2021 ... explaining, "I know things are going well."

"I talked to him last week," Licht told reporters Thursday ... "I know that things are going very well."

Brady had reportedly been dealing with pain in his knee throughout the 2020 season ... and had planned to get surgery once the Bucs' year concluded.

Licht said Brady is now in the rehab stage ... but he added he did not want to place an official timetable on a return to action for his team's superstar.

"I don't want to put an exact timeline on it right now because I don't want to set expectations one way or the other," Licht said.

"I think everybody thought was an April Fools' joke, but it was deadly serious."

That's CM Punk telling TMZ Sports what it was like to be ringside when MMA fighter Khetag Pliev had his FINGER RIPPED OFF in the middle of a match ... and it's one of the craziest stories ever!

Punk was calling the fight with his broadcast partner, John Morgan, at the Cage Fury Fighting Championship event in Philadelphia when the incident went down -- and says the most important thing was trying to stay focused.

"I wanted to make sure that I know that what I was seeing was correct," Punk says.

The scene inside the arena was wild -- especially since nobody could find Pliev's detached finger in the moments after the injury.

People were scouring the area with flashlights before ultimately discovering the severed digit in Pliev's fight glove.

Despite the chaos, Punk stayed relatively calm and continued to call the action like a true pro for the rest of the night.

"A lot of people are giving us props like, 'Congratulations, you didn't throw up!' ... but I was kind of right at home in the thick of it, calling it on the fly, as it happened. There's nothing better than live television."

Longtime NBA referee Leroy Richardson was due for a full-on ice bath Wednesday night ... 'cause the guy got banged up in not one, but TWO incidents while officiating a game -- including a shot to the family jewels!!

But, don't worry -- the ref recovered like a true champ and finished the game!! 💪

Richardson -- who's been a ref in the NBA for 26 years -- was working the Suns vs. Bulls game ... when Phoenix power forward Dario Saric accidentally smacked him right in the baby maker.

YEEEEEOUCH!!!

Saric immediately grabbed Richardson to apologize for the truly unfortunate nut shot ... and eventually, the ref was able to walk it off.

But, the bad luck continued with just 2 minutes left in the game ... when Chicago forward Denzel Valentine accidentally bumped into Richardson while contesting a 3-point shot ... sending the ref flying into the bench and tweaking his ankle in the process.

Either incident would have been a great excuse for a ref to leave the game -- but not Richardson. After all, he was in the Navy for 12 years ... so he's one tough dude!!

It hasn't been a great week for refs -- remember, NCAA official Bert Smith had a scary moment when he collapsed during an Elite 8 game earlier this week ... but thankfully, he's been in stable condition since.

John Cena's decision to participate in a Nickelodeon hidden-camera show helped an 8-year-old kid SAVE HIS BABY SISTER FROM CHOKING!!!

Seriously -- it's an unbelievable story!

8-year-old Jaxson Demsey was on a family outing in Hazleton, Pennsylvania over the weekend -- when he noticed his 20-month-old sister was having trouble breathing.

Fortunately for the Demsey family, Jaxson had watched an episode of the Nickelodeon show, "The Substitute" ... which featured a cameo from WWE superstar John Cena.

Cena was disguised as a CPR instructor on the hidden-camera show -- and was tasked with teaching a group of kids how to perform chest compressions in case of a choking emergency.

Clearly, the show made an impression on Jaxson -- because when his sister needed help, he sprung into action and successfully dislodged a McNugget!

“We were driving to my haircut, and I noticed she was starting to choke from a chicken nugget from McDonald’s," Jaxson told WNEP ... "I told my dad to pull over. Then I was starting to pat on her back, and it got out."

After the incident, he credited Cena for teaching him the life-saving skills he needed that day!

"In the very first episode [of 'The Substitute'], John Cena was on it, and in the last part, he showed how to save someone when they're choking."

Jaxon’s dad, Matt, was thankful his son stepped up in this situation, but he wasn’t surprised.

“He amazes us every day, you know -- some of the things he says and does, and his actions. We’re simply blessed to have the child that he is, the things that he does for his family, his friends, for his little sister. He’s a good big brother."

Claudia Conway's been hospitalized and thinks she might have appendicitis, but don't cry her a river ... 'cause she's dancing the pain away.

Kellyanne Conway's 16-year-old daughter revealed she's in the hospital by doing what she does ... posting it on TikTok. In the video, she's dancing from her hospital bed and flexing while attached to an IV. Not sure her doctors, or parents, would recommend that, but Claudia's gonna be Claudia.

She captioned the video, "Let’s hope that my appendix isn’t about to burst." She put the text, "drip too hard? yall rocking w/ IVs?" over the video ... a reference to Lil Baby and Gunna's track "Drip Too Hard." Yeah, she's a natural TikToker.

Claudia's status at the moment is unclear but based on her moves things may turn out OK.

The hospital trip comes a little over a week after Claudia was axed from "American Idol." Katy Perry applauded her, though, for taking control of her life, and invited her to audition again next year.

Luke Bryan hooked a big one on a fishing trip -- HIMSELF!!!

Luke did what country stars do -- hung out the gone fishing sign and headed for the lake in his pickup.

The "A.I." judge cast a line, but there was a snag -- in his hand. Yep, Luke rather calmly showed off a fish hook that sunk deep into his thumb ... in 2 places.

Luke and his guitar tech hightailed it to a doctor's office to get the hook removed, and even though it seemed excruciating, Luke was laughing as he shot video of himself and worried it might violate HIPAA!!!

It was so gnarly, Luke thought the hook penetrated down to the bone.

The backstory here ... before he started fishing, Luke reposted a pic of 2 cans of hard seltzer next to fishing rods. We're not suggesting alcohol was a factor, but we're not saying it wasn't either.

That didn't take long ... President Biden's dog, Major, is likely back in the dog house after a new biting incident at the White House, and this one sounds more serious.

A White House spokesperson tells us, "Major is still adjusting to his new surroundings and he nipped someone while on a walk. Out of an abundance of caution, the individual was seen by WHMU and then returned to work without injury."

As we reported, photogs got a shot of Major out for a walk Monday on the South Lawn, and he was on a leash. It's unclear who was walking the pup at the time.

Remember ... Major was sent back to Delaware earlier this month after he nipped at a White House staffer. The Prez said that time the bite didn't break skin.

A pro boxer's face swelled up in terrifying fashion after she was hit by an accidental head-butt during a fight Saturday night ... but fortunately, she says she's now recovering well.

Cheyenne Hanson, a 23-year-old German fighter, suffered the horrific battle wounds during her tilt with Alina Zaitseva in Germany ... with her face ballooning in size after the two women inadvertently clashed heads.

The post-fight pics of the damage to Hanson's face were insane ... the left side of the fighter's face BLEW UP -- and she had bruising all over.

In fact, Hanson showed off a before-and-after, side-by-side photo -- and she was damn-near unrecognizable!!!

But, Hanson on Monday revealed the swelling has gone down significantly ... though the bruising is still BAD.

Hanson was at least given a victory for her troubles ... the judges had her ahead in the fight at the time of the head-butt and awarded her the eighth win of her pro career.

Good news ... Ryan Switzer's infant son has undergone another major surgery ... and the NFL receiver says he's expected to make a full recovery.

Remember, Ryan's 10-month-old son Christian was hospitalized earlier this month after his parents found him in a pool of blood.

Doctors had performed surgery on Christian back on March 7 in order to track the cause of bleeding, but were not able to identify the issue with 100% certainty.

Ryan and his wife, Gabie, said doctors have made progress in the past few weeks and became certain they found the root of the problem ... and advised another surgery to address the issue once and for all.

Doctors at the famous Boston Children's hospital identified the issue as a "vascular anomaly" somewhere in his gastrointestinal tract.

Baby Christian underwent the procedure on Monday ... and his parents report everything appears to have gone well.

"Our sweet baby boy is stable and out of surgery," Switzer tweeted Monday. "This nightmare is over with. These wonderful people in Boston fixed our son. He’s going to make a full recovery. Praise God."

Lady Gaga's dog walker has finally been released from the hospital ... a little more than 1 month after he was shot in a terrifying dognapping incident.

Ryan Fischer was just discharged after a much longer stay than he anticipated ... due to complications with his lungs. Ryan says he was actually feeling pretty great just days after being shot and moving out of the ICU, and thought his recovery would be a simple process.

Unfortunately, Ryan says one of his lungs didn't cooperate and kept collapsing and it reached a point where he was readmitted for surgery to remove portions of it, and as he puts it ... "my recovery had become anything but a straight line."

The good news -- Ryan finally seems to be on the mend as he shared in an emotional video of himself getting dressed to leave the hospital, set to Carly Simon's "Coming Around Again."

Ryan knows his journey is going to be challenging though, saying ... "I'm finding my way in the outside world where triggers are real and working through trauma is WAY more than dealing with one unfortunate moment in life."

As we reported ... Ryan's been recovering ever since the February 24 dognapping incident. He had posted an update earlier this month when things looked pretty bleak ... showing him with a breathing tube in his mouth.

Thankfully, he also posted a more reassuring photo with the breathing tube gone. He detailed his near-death experience and the guilt he felt over not being able to protect Gaga's 2 French bulldogs, Koji and Gustav. The third dog, Miss Asia, walked over to him as he laid on the ground bleeding. He later called her his angel and Lady Gaga called him a hero.

Remember ... it's truly a miracle he's recovered as well as he has considering he was shot in the chest at almost point-blank range. The terrifying experience was captured on surveillance video from a nearby property, and he says that his doctors and nurses even told him they didn't think he'd make it.

As we first reported ... the thieves ultimately made off with Koji and Gustav and left Ryan begging for help on the sidewalk.

Whoa.

Look at Christian Vasquez's eye -- which he's LUCKY to still have after getting hit directly in the face with a baseball during a practice sesh.

The Boston Red Sox catcher revealed his scar Monday during a media session and explained how wearing sunglasses may have saved his vision ... and the whole thing is super scary.

Vasquez was working on drills on one of the practice fields at Boston's JetBlue Park complex Thursday when pitcher Hirokazu Sawamura fired a ball his way ... mistakenly thinking Vasquez was looking in his direction.

We know what you're thinking ... and no, video of the incident has not been released.

The ball struck 30-year-old Vasquez with such force, it opened up a nasty gash under his left eye -- requiring immediate medical attention.

Vasquez required several stitches to close the wound -- and says if it wasn't for the sunglasses, he might have lost his left eyeball.

"You like my scar," Vasquez joked with reporters Monday before giving a health update.

"I’m doing good ... “My eye is good. I can see perfect."

Vasquez then walked reporters through the incident -- "I saw the ball right here in my face and it knocked me down to the floor."

"The sunglasses saved my eye,” he said ... "If I don’t have the sunglasses, it was a different story."

And, get this ... Vazquez says he's "99% sure" he'll be ready to play Thursday for Boston's Opening Day game against the Baltimore Orioles.

Horrific scene on the NHL ice Sunday ... a star player for the Florida Panthers suffered a gruesome knee injury mid-game and was forced to leave the match on a stretcher.

Aaron Ekblad -- who was leading the Panthers in total ice time this season -- took a check from an opponent in Florida's game against the Dallas Stars when things went terrifyingly wrong.

Ekblad's knee and skate got caught under his body ... and when he came crashing down on top of the leg -- it all bent and crumpled awkwardly.

***WARNING: THE CLIP IS TOUGH TO WATCH***

You can see in video immediately after the injury ... Ekblad was in SERIOUS pain -- writhing on the ice, screaming, and holding on tightly to team trainers.

The defenseman was eventually strapped to a stretcher and taken off the ice. In a postgame update, Panthers head coach Joel Quenneville said Ekblad would be out indefinitely.

"It was pretty tough," Ekblad's teammate, Jonathan Huberdeau, told reporters after the game ... before adding, "You hear him scream too. I mean, it must have hurt so bad."

Jacob Blake's seeking more than damages for being shot and paralyzed by a Kenosha PD officer ... he wants the entire department held accountable, and he's striving to make his community a safer place going forward.

Attorney B’Ivory LaMarr, part of Blake's legal team, tells TMZ ... Jacob's case is not just about a lawsuit, it's about social justice. They want the City of Kenosha and its police force to take responsibility for the shooting.

LaMarr says this can begin in the form of a public apology to Jacob, his family, and Kenosha residents who are still suffering from the incident. He adds ... "In 2021, accountability should be the expectation, not the exception."

Next, Blake's team is calling for the Kenosha PD to step up and initiate reform and make changes to its protocols ... such as requiring all officers to wear body cameras.

LaMarr says there's an adversarial relationship between cops in Kenosha and the community, so the PD also needs to open a line of dialogue with the people and implement racial bias training.

Lastly, Jacob's team believes the City of Kenosha should reach out to help his children who witnessed the shooting ... and address the trauma they experienced from watching him get shot just feet away.

As we reported ... Blake's suing the Kenosha officer Rusten Sheskey for excessive force in the August 2020 shooting that left him paralyzed from the waist down. Blake's going after Sheskey for unspecified damages and he wants a jury trial. Sheskey was not criminally charged for the incident.

Jeff Lowe is attempting to recover from a stroke that left him unresponsive in an Oklahoma casino ... and he and his wife suspect someone slipped something in his drink that put his life in peril.

The 'Tiger King' star's wife, Lauren, tells TMZ ... Jeff was not breathing when she found him on March 18 around 3 AM at WinStar World Casino where they were staying. She quickly called 911, but says, "I thought he was dying in my arms."

Lauren says when EMTs arrived they determined Jeff was suffering a stroke -- and decided he had to be airlifted to a hospital in Denton, TX. She says the medical staff there worked miracles to limit the damaging effects of the stroke and save Jeff's life.

Lauren says what's strange is that doctors have run a battery of tests, and so far at least, haven't been able to determine what caused Jeff's stroke -- and that's made her very suspicious about something and someone.

She tells us on March 17, hours before the stroke, she and Jeff were out on a dinner date when a strange man approached them ... claiming he knew them and even knew their favorite drink orders. Lauren says they have no clue who he was, but he lingered when a crowd of 'Tiger King' fans gathered to take selfies with them.

Lauren says they suspect that's when this mystery guy spiked Jeff's drink with something that might have caused the stroke.

Jeff's blood and urine tests came back negative for commonly abused drugs ... according to Lauren, but she suggests the suspicious guy might have used something more exotic. She says they just started connecting the dots on what happened that night, and have not reported it to cops yet.

The good news is Jeff's now back at home recovering -- after spending 3 days in the hospital -- but Lauren says he's still having difficulties with speech and coordination.

Demi Lovato had a gut-wrenching, emotionally-charged reaction as she filmed her music video for "Dancing with the Devil," and TMZ has obtained the dramatic video.

Demi co-directed the music video with Michael D. Ratner, which they shot in the last week. The scene is a hospital setting, with Demi in a bed hooked up to all sorts of monitors -- mimicking the fight of her life after almost dying from an OD.

Production sources tell TMZ, Demi surprised everyone by saying she wanted to go off script and freestyle. Once the cameras were rolling, she began lip-syncing the song and began to sob uncontrollably.

As the song -- which was released Thursday night -- chronicled her journey as she lied about her addiction, her emotions got more and more intense.  At one point you hear Ratner say "Into camera" ...  Demi gazed into the lens and the sobbing became primal ... you can feel it even though you don't hear it.
