If Brock Lesnar wants a second UFC comeback fight, he may already have a taker -- heavyweight champ Stipe Miocic ... who says he's absolutely down to rumble with "The Next Big Thing."

We spoke with Miocic moments ago who told us he's excited to see Lesnar get back in the octagon -- but expressed concern over the fact BL's been out of the fight game for a couple years and could be rusty.

But if Brock crushes Mark Hunt at UFC 200 and wants a shot at the title -- Miocic says bring it on ... though he's pretty damn confident things won't work out well for Lesnar.

By the way, Miocic already fought Hunt in 2015 and kicked his ass.

Dana White confirms to TMZ Sports ... MMA reporter Ariel Helwani will never receive another media credential to another UFC event "as long as I'm here" ... but says he can still buy a ticket.

Brock Lesnar just announced his opponent for UFC 200 -- and also just bragged that he's making a "BOATLOAD OF MONEY."

Lesnar just appeared on ESPN and said he came up with the idea to return to the octagon on his own -- he wasn't courted back to the UFC -- claiming he felt he had unfinished business. He'll be facing 42-year-old Mark Hunt.

Lesnar had stopped fighting years ago after suffering 2 debilitating bouts of diverticulitis ... but says he still feels the burning desire to fight. So, he called up Dana White 3 months ago and asked to be on the UFC 200 card.

Lesnar said his comeback isn't about money ... but couldn't stop talking about how much money he's going to make -- saying his check will have a WHOLE BUNCH of zeroes. He didn't specify an exact amount.

Here's a shocker ... Dana White is FIRED UP about Brock Lesnar's return to the UFC -- telling TMZ Sports the ex-champ has been training like a beast and feels "like a million bucks."

With Muhammad Ali hospitalized in Arizona ... we asked UFC champ Robbie Lawler to tell us what "The Greatest" of all time means to him as a fighter.

Check out the clip ... it's nothing but respect and well-wishes for Ali.

Urijah Faber says he won't be doing any horizontal wrestling with Paige VanZant outside the Octagon ... 'cause the almighty BRO CODE would stop him from ever, ever, dating his super cute UFC teammate.

We got Faber out in L.A. doing a little press for UFC 199 .... and asked about the smokin' hot ... and apparently single ... Miss VanZant.

Basically, we wanted to know if there was any chance he'd make a run for the 'DWTS' runner-up ... and become the first couple of the UFC.

Urijah makes it clear ... it's NOT HAPPENING ... saying the fact Paige dated his (and her) teammate, makes any extracurricular grappling a clear violation of the almighty bro code.

Bonus awesomeness? Faber also talks to us about his signature butt chin ... and tells us who he thinks has the most iconic booty face in the history of Hollywood.

UFC star Michael Bisping says the producers of of Vin Diesel's new "XXX" movie actually lucked out when Conor McGregor dropped out ... cause they got him instead, and he's a real deal thespian.

We got Bisping out in L.A. and asked him about filling in for Conor on the new flick, which McGregor was slated to star in but then dropped out of.

Bisping makes it clear to us ... he's no replacement ... saying a whole new part was written for the movie and he had to audition to get it.

As far as talking about McGregor's acting abilities ... Michael says there's not much to talk about -- saying Conor's never even done it before ... while he has over ten credits on the all-important IMDB.

We looked it up ... he ain't lying.

Luke Rockhold is a perfectionist ... especially when it comes to sculpting male genitalia.

The UFC superstar says he's mad at himself for the makeshift dong he created for a prank he pulled on his friend during training camp. And if you haven't seen it yet ... it's pretty hilarious.

Long story short ... Luke decided to mess with a friend who passed out while suntanning -- and cut out a silhouette of a penis to put on his back ... to create a penis-shaped sunburn. Hilarious.

Problem is ... Luke says he coulda done better.

Nothing but class from Holly Holm's camp after her upcoming opponent was involved in a violent robbery in Peru -- with Holm's reps telling TMZ Sports they're glad Valentina Shevchenko is safe.

Shevchenko -- who's set to fight Holm at UFC on FOX 20 in July -- wasn't harmed in the robbery but her trainer was shot in the stomach while exchanging gunfire with the robbers.

"We are glad [Shevchenko] is safe," Holm's rep tells us ... "We wish her coach well."

Dana White has said he's not sure if the fight will go on as planned -- considering the incident may have traumatized Shevchenko -- but Holm's camp tells us Holly is still training as if it will happen.

"The fight is on as far as we know."

6:23 AM PT -- We just spoke with Valentina Shevchenko who says she will NOT back out of UFC on FOX 20 ... telling us straight up, "I will fight Holly."

When asked about her health, she told us, "I am feeling good. No injuries. Just a few days was a very big stress to me. I’m just starting to feel better now.”

UFC honcho Dana White says he's not sure if Valentina Shevchenko will still fight Holly Holm in July -- after V.S. dodged bullets in a bloody shootout in Peru ... calling the incident "madness."

As we previously reported ... Shevchenko and her trainer were eating at a chicken restaurant when 3 masked gunmen barged in and began robbing the place.

Shevchenko's trainer pulled out a gun and began firing -- killing one of the robbers ... but he suffered a gunshot to the stomach in the process. Shevchenko escaped unharmed. Her trainer is being hospitalized and is expected to survive.

Wednesday night, White told us he's unsure if Shevchenko will fight Holm at UFC on Fox 20 in July -- but seemed to understand if she decides to pull out.

"When things like that happen, it puts you in touch with your mortality," White said.

Meantime, Shevchenko has issued a statement of her own -- calling her trainer a hero ... whose quick actions saved her life and the lives of the other patrons.

The UFC fighter who's scheduled to take on Holly Holm in July miraculously escaped injury in a violent shootout in Peru ... though her trainer was shot while exchanging gunfire with the bad guys.

The woman caught in the crossfire is Valentina Shevchenko -- who was reportedly dining at a restaurant in Lima when three gun-toting men in motorcycle helmets came in to rob the place.

Wanna REALLY kick someone's ass? Pay attention ... Master Van Damme will teach you.

It's time for a lesson in Jurassic swag, courtesy of UFC fighter Derrick "The Black Beast" Lewis ... who dropped $125k on the a golden T-Rex motor thingy ... and TMZ Sports has the pics.

Lewis hit up Joseph McCamish of Etune Autosports in Houston and told the man he wanted "the baddest T-Rex he could build" ... and was willing to pay big bucks for it.

We talked to McCamish who tells us his guys were up to the task and created a one-of-a-kind ride for the Octagon god.

What'd they do? A full air ride system, custom-made leather seats, a black suede steering wheel, JBL audio system, a custom fabricated body kit and the piece de resistance ... a custom gold body wrap.

Final price for the whole thing ... $125k!!

Sylvester Stallone says he'd definitely pay good money to see Floyd Mayweather fight Conor McGregor -- though he's pretty sure Floyd would beat that ass!

Miesha Tate says Ronda Rousey is "somewhat emotionally unstable" -- and says it explains why the UFC legend went off on Paige VanZant at a party last month.

Tate appeared on Rush Fight Club on SiriusXM -- and went off about the issue when asked about the April encounter, when Rousey cussed out PVZ for congratulating Holly Holm after UFC 193.

"I think Ronda is somewhat emotionally unstable and I think that's been characteristic for a long time," Tate said.

"Doesn't mean she fights any worse for it. I'm not knocking her as an athlete but emotionally she's just got some things that are a little bit strange and I think that that was one of them."

Tate says the incident brought her even closer with VanZant -- despite the fact Tate says she would've handled the encounter in a much different way.

"This is why I feel like I identify with Paige more. She's so kind and when this whole thing happened she was like, 'We're emotional beings and hopefully I can make it right with Ronda,' and she's still such a sweetheart but I'm not that way."

"When Ronda does things like that to me I'm just like, 'No, eff you.' I'm not gonna bow down and not say how I feel."

This is no "Punk'd" ... Ashton Kutcher is a LEGIT jiu-jitsu fighter -- and his legendary trainer tells us he truly believes AK could beat up Conor McGregor in a ground fight.

Kutcher's been training with Brazilian jiu-jitsu master Rigan Machado -- an 8th degree black belt -- who tells TMZ Sports the actor is a natural ... "He is my #1 student."

Not only is Kutcher tough as nails, but Machado says the 38-year-old could be one of the top BJJ fighters in the world if he wanted to go pro.
