McGregor's UFC 264 trilogy ends in ankle injury as Poirier dominates first round

The fight lasted four minutes and six seconds. Conor McGregor rolled his ankle at the end of the first round of his trilogy bout against Dustin Poirier at the T-Mobile Arena in Las Vegas on July 10, 2021, and the doctor stopped it before the second could begin. What might have been a competitive night—McGregor moved with more fluidity than he had in their second meeting months earlier—ended instead with the Irishman bloodied, bruised, and unable to continue.

Poirier had spent those four minutes methodically breaking him down. Two judges scored the opening round 10-8 for the Diamond, who controlled the action on the canvas and landed heavy strikes while McGregor struggled to find his range. The injury, when it came, was sudden and severe enough that medical intervention was required immediately. McGregor had entered the fight promising to send Poirier out on a stretcher. Instead, it was McGregor who needed help leaving the Octagon.

In the immediate aftermath, speaking to Joe Rogan with the sting of defeat still fresh, McGregor was defiant and bitter. He insisted he had been winning the striking exchanges, that none of Poirier's takedowns had come from checked kicks, that the fight was far from over. But beneath the bravado was the unmistakable tone of a man who knew the night had been taken from him by circumstance rather than skill. He directed his anger not just at Poirier but at Poirier's wife, Jolie, who had entered the Octagon after the stoppage. McGregor made crude remarks about her presence, about direct messages, about an after-party at a nightclub. It was the kind of post-fight commentary that revealed more about his state of mind than any technical breakdown could have.

The contrast was stark when Khabib Nurmagomedov, the former lightweight champion and McGregor's most famous rival, weighed in on social media hours later. Khabib offered straightforward congratulations to Poirier and wished him well in his upcoming title shot against Charles Oliveira. There was no gloating, no personal attacks, no attempt to reopen old wounds. Just a simple acknowledgment of victory and a gesture of respect toward what came next. The juxtaposition—Khabib's grace against McGregor's rage—became its own story, a measure of how differently two fighters could respond to outcomes beyond their control.

What remained unclear in the immediate hours was the full extent of McGregor's injury. A possible broken leg, the reports said. Possible. The medical details would emerge in time, but the fight itself was finished. McGregor's trilogy with Poirier, which had begun with a knockout loss and continued with another defeat, had now ended not with a decision or a submission but with an injury that neither fighter could have predicted or prevented. The narrative McGregor had wanted to write—redemption, vindication, a return to dominance—would have to wait for another night, another opponent, another chance.
