McGregor's knee buckles 69 seconds into UFC 329 comeback as Holloway wins by TKO

Conor McGregor’s five-year comeback lasted barely over a minute. The former two-division champion appeared to blow out his right knee just 69 seconds into the opening round of UFC 329 on Saturday night, forcing referee Mike Beltran to stop the fight and hand Max Holloway a TKO victory in Las Vegas.

McGregor opened aggressively, throwing a jumping roundhouse kick in the fight’s opening seconds, but replays showed him landing awkwardly, his right knee visibly giving way as he stumbled to the canvas. He attempted to fight on — throwing another head kick that sent him to his back — but Holloway capitalised, dropping down to land punches during two separate ground sequences in the round.

Each time McGregor tried to regain his footing, his knee buckled beneath him. Beltran had seen enough, waving off the contest at the 1:09 mark of round one. A visibly distressed McGregor sat in his corner receiving medical attention before being helped out of the octagon by his team, as a stunned Las Vegas crowd looked on in near silence.

Holloway, who had been hoping to avenge a loss to McGregor from 13 years ago, was gracious but clearly unsatisfied with how the rematch concluded.

“Give it up for Conor McGregor guys,” Holloway said in his post-fight interview. “What an absolute animal. He kept asking to fight on. You guys are lucky, there’s going to be a Holloway vs. McGregor 3 now. What can I say? I had him weak in the knees, I guess. It is what it is. So much hype for that. We’ve got to run it back one more time. For it to end like this, it sucks.”

The result is a deeply anticlimactic end to a comeback McGregor had spent months building up following a layoff that stretched back to his own serious leg injury in July 2021. The Irish superstar had been one of the most heavily promoted returns in UFC history, and the abrupt finish left the main event feeling unresolved for fighters and fans alike.

If the knee injury proves as serious as it appeared, McGregor could face another extended spell on the sidelines — potentially a year or more — before he could contemplate competing again. A second major leg injury of this nature raises serious questions about whether he will fight again at all.

For Holloway, the win moves him forward but leaves his rivalry with McGregor without a definitive conclusion. What comes next for either man remains unclear in the immediate aftermath of a night that ended far sooner than anyone anticipated.
