Conor McGregor just UNLOADED on Eddie Alvarez at the UFC 205 press conference at Madison Square Garden ... telling Alvarez to "suck these big Irish balls."

It was insane ... Conor walked onstage 15 minutes late rockin' a mink coat ... and proceeded to verbally attack Alvarez.

At one point, McGregor snatched Alvarez's belt off the table ... almost coming to blows before Dana stepped in.

Here's Ronda Rousey and her boyfriend, Travis Browne, at LAX ... and she's the picture of a woman on a mission.

"I'm gonna beat this dude down in front of everyone. We're gonna silence the country of Ireland." -- Eddie Alvarez

Conor McGregor ain't gonna make it to the 5th round when he faces Alvarez at UFC 205 -- so says Eddie who tells TMZ Sports when it comes to Conor's reign, "S**t's all gonna end on Saturday."

Eddie's supremely confident his hand will be raised when all is said on done -- but explains why he thinks the craziest fights that night won't be in the Octagon ... they'll be in the stands.

Miesha Tate might think Ronda Rousey is done with the UFC ... but she's definitely not done with Ronda ... 'cause she says she wants one more chance to kick Rowdy's face before she retires.

We got Miesha out in NYC gearing up for UFC 205 and asked her if she's open to a third bout with Rousey ... being that the first two haven't gone her way.

It was just last week that Tate told us she thinks Ronda's career is just about over ... but one thing's clear ... if Rowdy only has a couple fights left she wants to be one of 'em.

An NYPD cop was literally SHAKING IN HER BOOTS when she came face-to-face with Conor McGregor this week -- but she wasn't scared ... she was insanely starstruck!

The UFC superstar is in New York gearing up for UFC 205 on Nov. 12th -- and came face-to-face with an officer who told Conor she was Irish ... and he was her hero.

What ensued was some serious fangirling ... with the cop claiming, "Besides my kids being born this is one of the best days of my life."

Jon Jones says he is "very pleased" arbitrators in his doping case found that he's "not a drug cheat" -- despite the fact he tested positive for 2 banned substances.

After the UFC star failed a drug test in June, he faced a 1-year ban from the U.S. Anti-Doping Agency. The case went to an independent panel of arbitrators which determined his fate.

Although he was given the max punishment, Jones is taking solace in the fact arbitrators believed his story about innocently taking a sexual enhancement tablet that contained banned substances.

Jones had claimed he relied on his teammate who said it could enhance his sexual pleasure -- and admitted he didn't properly clear the pill with USADA.

In the docs, the arbitrators called his actions "reckless" -- but ultimately decided he is not a "drug cheat."

Now, Jones has issued a statement saying, "Being cleared of these allegations was very important to me."

"I have always maintained my innocence and I am very happy I have been cleared in any wrong doing pursuant to the allegations made that I had intentionally taken a banned substance."

"I have worked hard in and outside of the octagon to regain my image and my fighting career and will take these next eight months to continue my training and personal growth both as a man and a athlete."

Jon Jones won't be stepping into the Octagon until next year ... 'cause the UFC fighter was just slapped with a year suspension resulting from a failed drug test before UFC 200.

USADA announced the ruling Monday morning ... saying they "determined that Jones should receive the maximum one-year period of ineligibility for his anti-doping violation."

The 29-year-old superstar tested positive for clomiphene and letrozole -- anti-estrogen agents that are often used after a cycle of steroids to counter to the negative side affects.

Traces of the drugs were found in a urine test from June 16, 2016 -- an out of competition test leading up to UFC 200.

Jones was set to fight Daniel Cormier at UFC 200 on July 9th ... but he was pulled from the card 3 days before the event due to the failed test.

It's not all bad news for Jones. The suspension was backdated to the day the failed test was made public ... meaning Jones is eligible to return July 6th, 2017.

UFC legend BJ Penn is off the hook in his sexual assault case -- with prosecutors telling TMZ Sports there is not sufficient evidence to prove he attacked a woman last year.

As we previously reported, cops in Hawaii launched an investigation into Penn after a former writer on his website claimed BJ forced himself onto his GF in August 2015 and forcibly removed her clothes.

Penn adamantly denied the allegations and claimed the writer made the whole thing up as payback for being fired from BJ's website.

UFC announcer Joe Rogan has nothing but respect for Ronda Rousey -- but says he doesn't like hearing when fighters talk about the next phase of their career before they're done in the Octagon.

Everyone knows Ronda is one of Joe's favorite fighters -- and he heaped heavy praise on her at LAX this weekend. But when we brought up Ronda's recent announcement that UFC 207 would be one of her last fights before focusing on movies, Joe expressed some concern.

"It's exciting to see her to come back if she wants to come back, but whenever someone starts saying a couple more fights and then I'll go into movies, I go, 'Man, I don't like hearing that.' 'Cause when you have one foot out the door, you should probably put both feet out the door."

Rogan added, "But she might not REALLY have one foot out the door."

Ronda Rousey just got verbally annihilated by a female fighting goddess -- ex-boxing champ Christy Martin who ripped Ronda for being a bad role model, a bad champion and an idiot.

48-year-old Martin -- one of the greatest female boxers of all time -- went off on Rousey to FightHype.com ... saying she wishes she was 10 years younger so she could teach the UFC superstar a lesson.

Check out why Christy thinks Ronda will never set foot in the Octagon again ... despite having a scheduled fight in December.

UFC star Cowboy Cerrone says he's 100% sure about one thing regarding UFC 205 -- which he's fighting in -- and that's by time it happens Donald Trump will be the President-elect of the U.S.A.

Cerrone has an Octagon brawl on November 12 against Kelvin Gastelum ... but when we got him out in L.A. we wanted to know his thoughts about a bigger fight happening that week ... Trump vs. Clinton.

Check out the clip -- Cowboy makes it totally clear he's team "Make America Great Again," saying that by the time he arrives in NYC for the fight ... the Donald will be drinking celebratory champagne.

BTW -- Cowboy ain't the only UFC star down with Trump. If you remember ... his boss, Dana White, has actually stumped for Trump ... giving a speech for him at the RNC.

Way to score some points with the head man, Cowboy.

Greg Hardy has been training his ass off as an MMA fighter -- linking up with one of the top gyms in the country where he's been living and sleeping while working under the tutelage of an ex-UFCer.

TMZ Sports has learned ... the 28-year-old ex-NFL star has been training with American Top Team in Florida -- which Dana White once hailed as one of the top 5 MMA teams in the country.

We spoke with one of Hardy's trainers, Mike Brown -- a former UFC fighter who actually fought and BEAT Urijah Faber TWICE in his MMA career.

Brown says Hardy has been living at the training facility -- "He's staying in the dorms we have upstairs. It's for guys who are really in intensive training."

While at ATT, Hardy has been working out with legit MMA studs like King Mo -- who seems to have taken a liking to the ex-Pro Bowler.

So, how does Hardy look?

"He seems to have the drive and desire," Brown says ... noting that Hardy has been taking classes in multiple disciplines to hone his skills.

"He took boxing last night, jiu-jitsu today. He was training with Steve Mocco, our wrestling coach, who was in the Olympics."

As far as taking a pro fight, Brown says there's a shot he could debut in 2017 taking a low-level pro fight or an amateur fight. Stay tuned ...

Miesha Tate says the Ronda Rousey farewell fighting tour might be pretty short ... like, one fight short ... telling TMZ Sports Rousey will retire immediately if she loses to Amanda Nunes at 207.

Little backstory ... Tate and Rousey hate each other ... and pretty much always have.

So, when we got Miesha out in L.A. we wanted to know how she felt about the news Ronda's career is winding down ... did she shed a tear, or pop some champagne when she heard?

Apparently she did neither ... and that's because she saw the whole thing coming. In fact, Tate says if Ronda loses her next fight, she'll quit right there.

There's obviously no love lost between the two ladies ... but still, if you've heard Ronda talk lately you kinda get the feeling Tate is onto something here.

Ronda Rousey's MMA career is almost over, but her PRO WRESTLING career could just be getting started -- because Stephanie McMahon says she's got her sights set on the UFC legend.

Vince's daughter -- who also happens to be a minority owner and a HUGE honcho with the company -- was in NYC when we asked if the WWE had already begun the courting process.

FYI, Rousey is a BIG pro wrestling fan -- and not only made a cameo last year -- but regularly attends pro wrestling events around the country.

Dana White just made it official ... Ronda Rousey's time in the UFC is winding down ... telling TMZ Sports he's spoken to her at length about the end of her career in the Octagon.

Ronda dropped the bombshell news during a recent appearance on 'Ellen' telling a shocked crowd that her upcoming fight at UFC 207 would be one of her last.

We talked to Dana out in Beverly Hills ... and asked if he's talked to RR about hanging it up (he's her boss after all) ... and White delivered the bad news ... it's real, and it's happening, just not quite yet.

Ronda Rousey's days in the Octagon are coming to an end ... so says the UFC superstar who just announced that UFC 207 is "definitely one of my last fights."

Rousey sat down with Ellen (airs Tuesday) and was asked about her MMA future -- and the 29-year-old made it clear she's thinking about the next phase of her life.

As for her upcoming fight against Amanda Nunes on Dec. 30th, Ronda says she's in killer shape and ready to throw down -- "I finally feel like super ninja good."
