UFC

The next time you're murdered by a blood elf rogue in World of Warcraft ... there's a good chance the person killing you is Ronda Rousey.

Turns out, the UFC star is SUPER into World of Warcraft -- and that's actually how she became friends with Vin Diesel on the set of "Furious 7."

Here's Ronda Rousey's badass comeback "Rocky" style montage -- complete with grueling workout sessions, full-speed wind sprints ... and a sick look at her mansion in the hills.

It's all part of the new promo for UFC 207 on Dec. 30 in Vegas -- and the message is clear ... Ronda has heard all the doubters and haters and CAN'T WAIT to prove 'em all wrong.

She's your problem now, Amanda Nunes.

IT'S TRUE!!

Conor McGregor DID shoot some scenes for "Game of Thrones" -- and will appear on the show next season ... so says Dana White.

The UFC honcho appeared on "Fox Sports Live" with Jay and Dan and confirmed Conor will be mixing it up with the Starks and the White Walkers and the Lannisters and everyone else n Westeros! (go to 4:30 in the clip)

"I knew that a few months ago that they were interested in putting him in the show," White said ... "And I'm glad he did it. It'll be great."

Dana didn't expand on McGregor's role -- but he's gotta kill someone, right????

Conor McGregor wants everyone to know he still has BOTH of his UFC championship belts -- and ain't NO ONE gonna take 'em!

The problem ... obviously ... is that the UFC has said Conor relinquished his featherweight championship last weekend because he can only defend 1 title at a time. He's keeping his lightweight title.

But Conor sees it differently -- he believes the "title" belongs to whoever physically holds the championship belts ... and as long as he has both belts in his possession, he still considers himself the "champ champ."

In fact, he took his belts on a private jet flight Monday morning.

Conor McGregor believes he's got all the advantages in a fight with Floyd Mayweather -- power, reach and youth ... saying, "Age waits for no man!"

McGregor talked about his possible boxing career during an event in Northern Ireland on Friday -- when, of course, the topic of Mayweather came up.

"If I focus with the work ethic I have solely on the sport of boxing, there’s no telling what I could do,” McGregor said.

"I would not go in there just to show up, I’d go in there to knock [Floyd] out. That’s it. He can be hit, he’s been hit before. Age waits for no man."

"I know the size is on my side, I know the reach is on my side, I know the youth is on my side."

He continued, "There’s a lot to lose for them, so that’s why they're scrambling ... but that’s okay, I’ll leave them scrambling. I’ve got some other boxing opportunities and potential opponents in mind. Some previous Floyd opponents. They can bring in anyone in the game. We’ll see what happens."

Someone brought up boxing champ Paul Malignaggi -- who called McGregor out on social media.

Conor's response? WHO THE F**K IS THAT GUY?!!

UFC tough guy Max Holloway says he's TEAM LEGALIZE WEED ... even though he doesn't smoke it himself.

After Nick Diaz spelled out why the UFC should do away with pot as a banned substance, we asked Holloway for his thoughts ... and he told us he's on board with the benefits of medical marijuana.

But the funniest part of this clip ... when he calls out Anthony Pettis -- diagnosing the UFC fighter with a case of "pussy-itis" ... and informing him, "I got the vaccine!"

Good news and bad news for Conor McGregor ...

GOOD NEWS: Northern Irish boxing superstar Carl Frampton -- the reigning WBA featherweight champ -- says he loves Conor and would be down to train with the guy if he's serious about boxing.

If Conor McGregor actually gets his $100 MILLION boxing match with Floyd Mayweather, you'll never see him compete in MMA again ... so says Tyron Woodley.

Tyron makes it clear, he wants NOTHING MORE than to fight Conor at UFC 209 ... but would totally understand if McGregor turns him down for the life-changing payday.

He also suggests Conor's decision to get a boxing license could just be a power move to stick it to the UFC -- which recently made CM relinquish his featherweight title.

One last thing ... Woodley -- who's been beefing with Conor since their backstage run-in at UFC 205 -- says he actually respects the guy for what he's done for the sport.

See, these guys can play nice.

UFC superstar Nick Diaz says he's the "face of weed for athletes" ... and isn't afraid to admit it.

In fact, Diaz says he's the "Number 1 athletic stoner besides Michael Phelps."

Diaz -- who's tested positive for weed on several occasions -- appeared on "The Jasta Show" and explained why athletes should be ALLOWED to smoke marijuana ... especially after a fight.

You gotta listen to Diaz explain it ... but essentially says he relies on weed to get his head right ... especially after he's been knocked out and he's discombobulated.

Diaz admits weed can be performance enhancing ... but no more so than vitamins.

There's also this ... Nick says his brother, Nate Diaz, was NOT smoking CBD oil after his UFC 202 loss to Conor McGregor -- he was blazing up good ol' fashioned weed.

Rising UFC star Khabib Nurmagomedov is FREAKING INSANE!!!!

Don't believe us? Listen to the man himself casually describe to TMZ Sports how he SPARS WITH LIONS as part of his training.

You heard us ... lions, like Simba and Mufasa except real and not animated ... meaning totally capable of ripping your face off at any minute.

He's conquered the wild before ... there's actually video of him wrestling with bears as a child ... but good news for all you Smokey's and Yogi's out there, KN says he's moved on to lions permanently.

If CM Punk wants to fight again ... he should take his talents somewhere OTHER than the UFC ... so says the man who beat his ass, Mickey Gall.

Gall is gearing up for his big showdown with Sage Northcutt at UFC on FOX 22 in December ... a fight he asked for after defeating CM Punk at UFC 203.

Couple things ...

1) Gall fires back at Sage's training partner, Tyron Woodley, who said Mickey bit off more than he can chew.

2) He delivers some health advice to CM Punk, who recently said he wants a 2nd fight in the UFC -- don't do it.

UFC rising superstar Khabib Nurmagomedov says he wants to HUMILIATE Conor McGregor -- and vows to "finish his hype" forever if Dana White gives him the chance.

TMZ Sports spoke to the fighter (who's currently in Russia!) and he explained the fight isn't about the money because "I have a lot of money."

Khabib says Conor simply rubs him the wrong way -- and he wants to punish the Irish superstar ... badly.

"I want to take him down, speak with him, slap him, make him nervous ... like, 'Hey, get up! Let's go! Where is your boxing?' ... play with him and make him give up. This is what I want."

"But I don't want to finish him 1st round, 2nd round, 3rd round ... I want to fight with him for 25 minutes like 5 rounds and I want to make him look very bad. And finish his hype."

Khabib also describes a backstage confrontation with Conor at UFC 205 -- and says he's no Eddie Alvarez or Tyron Woodley ... and would've destroyed CM on the spot if he hadn't retreated.

There's more ... Khabib also explains why he no longer gets into street fights (spoiler: it's because he's afraid he might kill someone).

If Tito Ortiz didn't get a piece of the UFC, Conor McGregor ain't got a chance in hell at ownership ... so says Tito himself.

The UFC Hall of Famer was leaving Delilah restaurant in L.A. this weekend when we asked about Conor's ownership demands ... and the fact Mark Wahlberg has offered McGregor a piece of his stake.

Floyd Mayweather ain't letting himself go in retirement -- his bodyguards say the dude is still in INSANE shape and could fight RIGHT NOW if he wanted to.

TMZ Sports spoke with Floyd's muscle -- Greg and Jizzy -- at the Money Team record label launch party in New York ... when they told us why they're convinced Floyd could fight 'til he's 60 YEARS OLD.

Ask and you shall receive!

Conor McGregor says he wants to own a piece of the UFC -- and Mark Wahlberg says he's willing to give it to him.

Nick Diaz was inside 1 Oak nightclub when Conor McGregor went off on Floyd Mayweather Tuesday night -- and had this 2 word reaction -- "F*** you."

Diaz began Snapchatting himself during Conor's rant -- and said, "I was already the 2-weight world champion, bitch."

Then he threw up a middle finger and said, "F*** you."
