Cris Cyborg says she's not sweating Holly Holm's famous leg-striking power -- it's Holly who should be worried about Cyborg's fists.

The UFC superstar joined the guys on the "TMZ Sports" TV show (airs tonight on FS1) -- and told us why the former bantamweight champ should be afraid ... very afraid.

Cyborg vs. Holm is the main event at UFC 219 on Dec. 30 in Vegas -- and Cris says she's trying to rally her fans to help out the kids at the local hospitals while she's in town.

UFC legend Chuck Liddell says there ain't a chance Floyd Mayweather steps inside the Octagon -- 'cause any MMA fighter would beat the living hell outta him!!

"C'mon man -- he can't fight in the UFC," Chuck told TMZ Sports.

"Why would he do that? He's just gonna get hurt."

The Iceman, who was out visiting a children's hospital, clearly thinks Floyd wouldn't stand a chance in an all-out scrap ... and told us it'd be over quick if he rematched Conor McGregor.

Floyd Mayweather moving over to MMA just got the thumbs-up from Holly Holm -- who says she could see TBE knucklin' up for the UFC ... and goin' after it with all he's got.

"I'm sure he won't mind putting in the work if he decides to do something with MMA," Holm told the guys on "TMZ Live."

If anyone would know, it'd be Holly -- who won 18 TITLE FIGHTS in boxing before she became a UFC superstar.

But HH -- who's fighting Cris Cyborg at UFC 219 -- ain't saying it's gonna be easy ... in fact, she told us one area where Mayweather's REALLY gotta work if he doesn't wanna get wrecked.

FYI, Floyd shot down fighting for the UFC on Wednesday after Dana White said they were in talks ... but, in the same breath, said the door's always open.

If Floyd Mayweather's serious about stepping inside the Octagon -- there's a UFC champion, not named Conor McGregor, who says he'll (respectfully) kick his ass!

We spoke with T.J. Dillashaw after Dana White said he was "talking to Floyd" about a UFC deal ... and the bantamweight champ threw down the gauntlet on Mayweather.

"Floyd, bring it," T.J. said to TMZ Sports. "Let’s find out what real fighting’s all about."

But as much as Dillashaw would "love" to welcome TBE to MMA ... he's not giving Floyd a chance in hell of surviving.

"Not against me, that's for sure ... he's toast."

Demetrious Johnson thinks Floyd Mayweather would be EASY WORK in the octagon -- telling TMZ Sports he'd obliterate the boxing superstar if the two clashed in the UFC.

After Dana White confirmed he was talking with Floyd about a "UFC deal" ... DJ immediately threw his name in the mix as a possible first opponent.

In fact, Mighty Mouse joined the guys on the "TMZ Sports" TV show (airs weeknights on FS1) and broke down exactly how he'd punish the 40-year-old.

Here's Floyd Mayweather shooting down a potential UFC fight ... while at the same time leaving the door open.

Yeah, we know ... it's confusing -- but the takeaway is that Floyd wants everyone to know he has NOT signed a deal with Dana White.

After White told ESPN he's "talking to Floyd" about a potential MMA deal -- Floyd spoke with FightHype and said, "I'm not doing it."

But in the same breath ... he also bragged about how much money he could make with the UFC and added, "We just don't know what the future holds for Floyd Mayweather."

Remember, Floyd RETIRED before the Conor McGregor boxing match and swore he was done fighting forever ... only to go back on his word to take the fight.

If Floyd Mayweather is serious about taking a UFC fight, he's already got a WORLD CHAMP offering to train him -- Tyron Woodley!

"Let me know when you need me to slide through -- we'll get you trained, get you ready," Tyron said on "The Hollywood Beatdown."

Tyron and Floyd are friends -- and during the show (full ep drops Friday on the TMZ Sports YouTube channel) Woodley says he REALLY hopes Mayweather's first UFC opponent is Conor McGregor.

"Conor is the only option for him," Woodley says ... noting McGregor is "really a stand-up fighter" and doesn't pose as big of a threat as other UFC stars who specialize in wrestling or jiu-jitsu.

Tyron says he's excited for his pal -- and wants to walk him into the Octagon once the ink is dry on the contract!

Make sure to catch Tyron EVERY WEEK on "The Hollywood Beatdown."

The UFC is talking to Floyd Mayweather about a REAL fight in the octagon ... with Dana White saying it's a "realistic possibility."

"We're talking to Floyd about doing a UFC deal," White told ESPN.

"It's real. He was talking about [boxing] Conor McGregor. Was that real? Have you heard Floyd talk about many things that aren't real? He usually tips his hand when he's in the media and then that sh*t ends up happening."

White added, "We're interested in doing something with Floyd. Everything is a realistic possibility. Mayweather vs. McGregor f*cking happened. Anything is possible."

Stay tuned ...

Khabib Nurmagomedov says he's going "The Walking Dead" route to make weight at UFC 219 -- telling TMZ Sports he'll hack off his own leg to hit 155 pounds in 10 days.

Don't worry -- he's kidding ... we think.

"I’m gonna cut my leg ... right or left, I don’t know," Khabib told us out in Century City.

On the real, Nurmagomedov says he's sick of everyone hating on his diet ... after a weight-cutting issue forced him outta his fight with Tony Ferguson back in March.

Speaking of Tony ... Khabib says he could whoop both Ferguson and Conor McGregor IN THE SAME NIGHT ... and he seemed dead serious about that, too.

"I will f**king gut you! I will make you bleed. Pain. Pain. A lot of pain."

That's Tim Kennedy -- UFC and U.S. Army Special Forces vet -- telling all the internet trolls what he's gonna do to them for spoiling "Star Wars: The Last Jedi."

Tim's a HUGE Sci-Fi guy ... but says he still hasn't seen the movie 'cause he's too busy being a badass in the desert.

Kennedy tells TMZ Sports he's pissed 'cause he can't touch social media -- "there's a bunch of a**holes out there trying to ruin it for people like me!"

So, if you spoil the party -- like UFC contender Colby Covington did on Thursday -- Tim says he's literally gonna cut you open and let you bleed out.

Yeah ... the force is strong in this one.

Here's a painful lesson on why you should NEVER get in a street fight -- courtesy of UFC star "Platinum" Mike Perry.

We asked Platinum -- who fights this weekend at UFC on FOX 26 -- to give us the lowdown on if he's ever had to throw down outside the Octagon ... and the story he hit us with was Oscar-worthy.

It all went down on a New Year's Eve in DT Orlando ... when Mike and his GF, "Platinum Princess" Danielle Nickerson, were out celebrating on the streets.

Perry says a random guy was dumb enough to hit on Danielle when they were clearly together ... and fire on Platinum after he told him to step off!

Mike says he fired back with a left hook from hell ... and you can guess how that turned out.

The whole thing's pretty hilarious. Also, kinda terrifying.

UFC champ Tyron Woodley dropped bombs on Keaton Jones' parents in the newest episode of "The Hollywood Beatdown" -- explaining why they're even worse for him than his bullies at school.

Woodley says Keaton's dad needs to "get the hell slapped outta him" for being a white supremacist ... and his mom should take a seat after allegedly trying to parlay Keaton's fame into a cash grab.

"Why do you need money to fight bullying? You need mentors ... you don't need money."

The champ says he's still got Keaton's back -- but advises him to cut out his folks, so he can become a better person.

Ronda Rousey and the WWE have been circling each other for months ... but sources close to both sides tell TMZ Sports Ronda has NOT put pen to paper -- not yet, at least.

It's no secret that there's serious interest -- Rousey's teased the move and even appeared in a backstage WWE promo ... and company honchos Triple H and Stephanie McMahon have both gone on record saying they'd love to have her.

But, multiple independent sources from all sides of the deal have told us contract talks have NOT gotten off the ground.

As one source bluntly put it, "[Ronda's team] hasn't begun any negotiations with the WWE."

Doesn't mean they won't hit the negotiation table in the future ... but as far as what's cookin' right now -- no deal.

FYI, we're told Rousey is still working out hard (unclear if she's doing specific wrestling training). She's also shooting for her role in Mark Wahlberg's movie, "Mile 22."

Busy lady.

If Keaton Jones REALLY wants to get bullies off his back, Rampage Jackson says there's only one way he can get the job done.

"I would kick somebody's ass!" Rampage told TMZ Sports. "You fight -- you go down swingin' -- they ain't gonna kill you, most likely."

The MMA star says the world's getting waaay too soft when it comes to bullying ... and throwing hands accomplishes something words never could.

"You get your respect and people won't mess with you no more. Most people are cowards, anyway. Most bullies are cowards."

And if Keaton needs to see how it's done, Rampage is scrappin' with Chael Sonnen at Bellator 192 in January.

Chael Sonnen is defending Roy Moore's refusal to throw the white flag in the Alabama Senate race ... saying there's no reason to concede if he still thinks there's a chance he can win.

TMZ Sports spoke with the MMA star about Moore continuing to fight his apparent loss to Doug Jones in Tuesday's election ... and Sonnen says it's perfectly fair to keep fighting 'til the very end.

Sonnen compares it to when Hillary Clinton didn't immediately concede to Donald Trump in the presidential race last year ... and sympathizes with both politicians for not wanting to acknowledge defeat.

Chael also gets into some fightin' talk about going up against Rampage Jackson at Bellator 192 ... and explains why he has ZERO confidence leading up to the fight.

What do you do when everyone in the world thinks you're trying to bang Rita Ora??

If you're Conor McGregor ... you take your REAL girlfriend on a luxury shopping spree!!

Check out the UFC superstar and Dee Devlin leaving the LV store in NYC with more than 11 BAGS (and that's only the bags we could see!).

Of course, Conor reportedly made around $100 mil for the Mayweather fight (so money ain't a thing) -- but it seems he's trying extra hard to make Dee happy.
