UFC superstar Dan Henderson says Michael Bisping can crack all the geriatric jokes he wants -- 'cause when the two face off in the Octagon, Bisping's gonna "end up getting his ass beat by an old man."

45-year-old Dan joined the guys on the "TMZ Sports" TV show -- and responded to Bisping's trash talk .. specifically when he said he wants to fight Dan before he dies of old age.

It's pretty good stuff ... Dan vows to whoop that ass -- AGAIN -- and says he'll retire right after he does.

He also gives us an update on the contract situation for the fight.

Check out the whole interview tonight on "TMZ Sports" on FS1.

Apparently, she's human after all ... 'cause UFC superstar Cris "Cyborg" Justino says she's in all sorts of pain after being bit by a BLACK WIDOW SPIDER!!

Cyborg says she was working in her garden last week when the spider appeared and sunk its fangs into the fighter's leg -- causing a nasty wound.

"My leg is in a lot of pain," Cyborg says.

Cyborg says she went to the doctor and got antibiotics and cream for the bite wound.

FYI, the black widow is one of the most venomous spiders in North America.

Yeesh.

UFC champ Michael Bisping says he wants to fight Dan Henderson ... before Hendo dies of old age.

It's pretty funny stuff ... Bisping is adamant he's not planning on retiring anytime soon -- telling TMZ Sports he wants to fight everyone from Hendo to GSP and even Rockhold again before he hands it up.

But the best part of the video is all the shade he throws at 45-year-old Henderson -- "Henderson's gonna die soon, so I might as well knock him out. I might as well put him in the grave."

Yeah, she's got a Hollywood agent now ... but Holly Holm is refusing to "go Hollywood" -- in fact, she just turned down a role in a huge movie to focus on her upcoming fight.

Our sources tell us ... Holm was contacted to appear in a major studio movie -- but respectfully declined because the film dates interfered with her final fight prep for UFC on FOX in July, where she'll take on Valentina Shevchenko.

We reached out to Holm's rep, Lenny Fresquez, who wouldn't comment on the movie situation -- but did tell us that Holm has been receiving "an unbelievable amount of calls" from movie and TV producers.

Fresquez says Holm recently hired the APA agency to handle the non-fight related side of her career -- but insists that her main focus is still taking care of business inside the Octagon.

Here's UFC smoke show Arianny Celeste showing off her insane physique during a bikini photo shoot in Puerto Rico.

They've said some pretty nasty stuff to each other ... but Daniel Cormier says there's ONE insult that pisses Jon Jones off more than anything else.

DC was out in NYC promoting his big fight with JJ at UFC 200 in July -- when he told us he knows exactly how to get under Jon's skin ... and doesn't plan on stopping anytime soon.

Bo don't know Brock ... apparently.

With Brock Lesnar referring to himself as "the modern day Bo Jackson" -- due to his UFC and WWE success -- we went right to the 2-sport authority and asked Bo himself how he felt about the comparison.

UFC badass Ronda Rousey's secret is out ... she's a big softy at heart.

Check out the book Rousey was carrying Thursday as she left Glendale Fighting Club. It's Jojo Moyes' wildly popular romantic novel "Me Before You," which was made into a major chick flick that came out last week.

Yup ... sometimes fighters need a good cry too.

"You go ... or they go."

That's how UFC fighter Valentina Shevchenko feels about her trainer's decision to pull his gun and fire at gun-toting thieves last month during an armed robbery in Peru.

Shevchenko joined the guys on the "TMZ Sports" TV show and broke her silence about what was going through her mind when 3 armed men stormed the restaurant where she was having dinner.

As we previously reported, her trainer, Pavel Fedotov, pulled his gun and fired at the robbers, killing 1 -- but was shot in the stomach during the exchange.

Shevchenko says Pavel is still hospitalized-- but hopes he'll be able to travel to Chicago to see her fight Holly Holm at UFC on FOX 20 on July 23.

So Nate Diaz has an N-word pass.

The UFC star was rollin' into Bootsy Bellows nightclub last night ... when he used the word (with an "a" not the "er") during a friendly exchange with a photog.

UFC champ Michael Bisping says Luke Rockhold was a real "a-hole" after UFC 199 -- insisting he TRIED to be respectful to Luke ... but Rockhold was too busy being a "sore loser."

FYI, Rockhold blasted Bisping on Instagram Tuesday morning ... calling the guy "classless" for refusing to shake his hand after beating him on Saturday night.

"I felt it was a classless move on his part," Rockhold said ... "I don't believe in kicking a man when he's down."

Bisping joined the guys on the "TMZ Sports" TV show (airs tonight on FS1) -- and said Luke's completely delusional because he actually tried to shake his hand TWICE.

By the way, Bisping also says he's not ready to retire just yet because a true champion defends his belt!!!

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.
