Dana White Says Mark Zuckerberg 'Absolutely Interested' In UFC Fight

Dana White says he's sure Mark Zuckerberg wants to take a fight in the UFC -- and, get this, he tells TMZ he's definitely not opposed to making the Meta boss' wish a reality.

White joined Harvey and Charles on "TMZ Live" on Thursday to preview this weekend's big UFC 292 card ... but before he talked Sean O'Malley vs. Aljamain Sterling -- he spilled the beans on what he knew about the failed Zuck vs. Elon Musk matchup.

He said both guys were dead serious about brawling ... but when Elon wanted to go more of an informal route with the bout -- Zuck decided to pull away.

"He and I talk multiple times a week," White said of Zuckerberg. "And we had dinner last Monday. He's very serious about competing. And when he mentioned it, he said -- listen -- what he was saying in response to Elon was there are tons of professional organizations out there and this is the way this should be done, not in some backyard or whatever Elon was saying."

He added that Zuck understood the fight would have to be sanctioned by an athletic commission, there would need to be proper medical testing and drug testing ... and when Elon didn't seem to get that -- he said Zuckerberg pivoted.

As for what's now next for Zuck ... White told the guys "I would say he is absolutely interested" in battling it out with a UFC fighter in White's org.

And, Dana said it's a possibility he makes it all happen.

But, until then, White's in Boston getting ready for a helluva fight on Saturday night between O'Malley and Sterling.
