​Conor McGregor has insisted that he was not carrying an injury as he prepared for his highly anticipated UFC 329 showdown with Max Holloway in Las Vegas. The Irish star’s comeback fight lasted barely a minute after he suffered a knee injury and retired from the contest, later claiming that the setback “came out of nowhere.”
A former two-weight world champion who had not fought since breaking his leg against Dustin Poirier in July 2021 attempted a flying kick to begin the opening round. He landed awkwardly, immediately appeared to be in trouble, and after a brief display of resistance, signaled to the referee that he could not continue.
On social media, clips circulated showing McGregor approaching the octagon and gingerly stepping out of his shoes, which some interpreted as evidence of a pre-existing issue. Yet the 37-year-old refuted those claims, saying on X (formerly Twitter): “My head gasket is gone. Destroyed. I had no injury going into the fight. I was throwing kicks, planted and jumping, all throughout camp as well as backstage before the fight. This came out of nowhere. I am beyond dark here. I can only describe it as hell.”
UFC president Dana White supported McGregor, arguing that any hint of a pre-fight injury would have been obvious during the public events leading up to the fight. He noted that the doctors had examined him before the bout, and that McGregor had appeared in good form at the press conference and weigh-ins. “Just on my accounts, the face-off has had 80 million views. So if there was a pre-existing injury, somebody would have noticed it. Nobody noticed anything,” White said.
Holloway, a former featherweight champion, indicated he would discuss the possibility of a rematch with McGregor once the Irishman has recovered. “It is what it is, I’m going to sit down with the UFC,” Holloway said. “There was so much hype for that right there. We’ve got to run it back one more time. One more time for the boys.”
Throughout his career, McGregor has faced a series of setbacks and distractions beyond the cage. After his leg fracture against Poirier, he was penciled in to fight Michael Chandler in June 2024, but the match was canceled after McGregor sustained a broken toe in training. The following year brought further legal and personal turmoil, including a jury in an Irish civil court finding him liable for rape in 2018, and in October 2025, an 18-month ban for “whereabouts failures” after missing three attempts by Combat Sports Anti-Doping to collect biological samples in 2024.
As the UFC universe processes this latest setback for McGregor, attention remains firmly fixed on what’s next for the former champion—whether he will pursue another high-profile return, and how Holloway and the broader MMA world will respond in the wake of this unexpectedly swift and dramatic turn of events.
