Joe Rogan has already issued a warning to Conor McGregor amid his latest controversy.
McGregor, 36, made headlines but for all the wrong reasons.
The Irishman was caught flooring a club reveller with two brutal punches in a Ibiza nightclub, with footage going viral.
He was pictured partying with a string of celebrities prior to the shocking incident.
A witness has since revealed what happened following the punch-up.
UFC boss Dana White has made his feelings clear on McGregor, who hasn't fought since his TKO defeat to Dustin Poirier back in July 2021.
The 'Notorious' was due to return to the famed Octagon at last summer's UFC 303 when he was matched against Michael Chandler.
But he was forced to withdraw from the Las Vegas event after he suffered a toe injury.

Rogan, who has commented on several of his fights, believes it would be 'really sad' if he came back in his late 30s and bemoaned his partying antics.
"He had a broken toe before his fight against Chandler," he said on his podcast last April. "I understand that. OK, why should you fight with a broken toe? Especially a guy who moves a lot like Conor, he relies on movement so much. Yeah, I get it. So heal that toe up. What’s that, two months? And so then you’re back in camp, and then you reschedule a fight, and then you fight again. But he didn’t."
Conor McGregor has not fought in the UFC for almost four years. Image: Getty Rogan added: “Also partying, constant partying. All these legal problems that he has, scooting around on yachts, and driving around in a Lamborghini. He’s wealthy. What’s really sad is if he comes back when he’s like 39 or 40 and his body just doesn’t have it anymore.”
The UFC commentator also delved into his social life and isn't convinced he will fight again.
"When you hear guys are doing coke, that one’s the worst, that’s the one that deteriorates you more than anything," he explained. "That’s a scary one for fighters too because the thrill of cocaine is exciting for people who like exciting things. Fighters are adrenaline junkies that like to be pumped up.
"Conor seems to enjoy it which is one of the things that makes me bet he probably won’t come back."
