Conor McGregor’s highly anticipated UFC comeback came to a heartbreaking end after just 69 seconds when he suffered a serious knee injury during his rematch against Max Holloway at UFC 329. Nearly five years after breaking his leg against Dustin Poirier, the former two-division champion endured another cruel setback as his right knee gave way while attempting a jumping kick early in the opening round. Initial assessments suggest McGregor may have torn his ACL, an injury that could require between nine and 18 months of recovery depending on its severity.
Despite the disappointing result, McGregor broke his silence shortly after the fight. Around two hours after the contest was stopped at T-Mobile Arena in Las Vegas, the Irish star shared a statement on social media, offering fans an early insight into both his physical condition and his mindset following the devastating injury.

Conor McGregor did not wait long before addressing fans following the injury that abruptly ended his UFC 329 comeback. Less than two hours after his rematch against Max Holloway was stopped just 69 seconds into the opening round at T-Mobile Arena in Las Vegas, the former UFC champion took to social media to share an emotional update on how he was feeling.
“My head gasket is gone. Destroyed,” McGregor wrote on X. “I had no injury / injuries 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.”

While the full extent of the injury has yet to be confirmed, UFC CEO Dana White revealed after the event that doctors believe McGregor may have suffered a torn ACL. Videos circulating online also showed the Irish fighter leaving T-Mobile Arena barefoot, shirtless and still wearing his fight shorts as he limped toward further medical evaluation, with additional tests expected to determine the severity of the setback.
How Conor McGregor’s UFC 329 Comeback Ended in Defeat
Conor McGregor’s long-awaited return to the Octagon came to an abrupt end just 1:09 into the opening round of his UFC 329 main event against Max Holloway. The former two-division champion suffered a serious knee injury after throwing an early jumping kick, landing awkwardly and struggling to regain his footing. As he repeatedly lost his balance and was unable to continue, referee Mike Beltran stepped in to stop the contest, handing Holloway a first-round TKO victory.
Making his first appearance since July 2021, when he sustained a broken leg against Dustin Poirier, McGregor started the fight aggressively inside T-Mobile Arena in Las Vegas. However, his explosive approach quickly backfired as successive jumping attacks appeared to aggravate his right knee. The injury left him unable to stand properly, bringing the highly anticipated rematch to a disappointing close after only 69 seconds.
The sudden finish stunned fans inside the arena, with McGregor clearly unable to put weight on his injured leg as he left the Octagon. After the fight, the Irish star admitted his frustration over the unexpected setback, while UFC CEO Dana White acknowledged that the injury had overshadowed what was expected to be one of the biggest comeback stories in recent UFC history.
