Retired UFC lightweight champion Khabib Nurmagomedov says he is doubtful that Conor McGregor will ever step back into the octagon again following his TKO loss to Dustin Poirier Saturday night.

"Money and fame show who you are," Nurmagomedov told ESPN. "All the time we hear that money and fame change people. No. When money and fame come, these two things show who you are. And what has [McGregor] done? He punched an old guy [in a bar in 2019]. You guys can watch everything he did and understand, it's just like Dustin said, 'This guy is a bag of s---.'

But McGregor is big money for the UFC, Pay Per View sales and the sportsbooks.

Dave Mason of BetOnline confirmed Poirier-McGregor 3 was the most wagered on UFC fight in his company's 22 plus year history.

BetOnline is already taking bets on McGregor's next opponent.

Khabib expressed further disgust over McGregor's antics and the direction in which the UFC is going by supporting the Irishman.

"I saw a lot of tweets try to support him. How are you gonna support this guy? When kids, young generation watch him, watch this sport? If you want to promote your fight, promote.

"If the MMA community is going to support this bad people, this sport is going to go in a bad way."

Beyond the attitude, Khabib says McGregor's leg injuries will prevent him from excelling any further in the UFC.

"Without broken legs, yes, [he could be the same]," Nurmagomedov said. "But with broken legs, he's never going to kick the same. With him, no, I don't believe [he'll return to the top]. Conor have good age [32], but what happened with his mind, legs -- this guy is finished, but he's good for promotion."
