Conor McGregor blows out his knee, comeback ends in just 99 seconds as Max Holloway wins UFC 329 main event

Conor McGregor's comeback lasted 1:09 before a catastrophic knee injury ended his UFC 329 main event against Max Holloway. The former two-division champion threw a jumping roundhouse kick to open the fight but landed awkwardly on his right knee, immediately compromising his ability to compete.

McGregor attempted to continue fighting despite visible distress, attempting another head kick that left him on his back as Holloway pursued ground-and-pound. A subsequent slip put McGregor down again, and when he struggled to rise with his knee buckling beneath him, referee Mike Beltran waved off the contest. The Las Vegas crowd sat in stunned silence as McGregor's first fight in five years ended in anticlimactic fashion.

Holloway secured the technical knockout victory but acknowledged the hollow nature of the win. "What an absolute animal," Holloway said of McGregor. "He kept asking to fight on." He called for a third meeting: "We've got to run it back one more time. For it to end like this, it sucks."

The injury could carry long-term consequences for McGregor. A serious knee injury of that magnitude typically requires months of rehabilitation—potentially another year-long layoff at minimum. At 35, with a five-year absence already behind him, such a setback raises questions about whether McGregor's comeback can realistically continue or whether the injury might effectively end his fighting career. Holloway advances but loses the satisfaction of a competitive victory over an old rival from 2013.
