Conor McGregor suffers devastating injury to end UFC return in 69 seconds

Conor McGregor's highly anticipated UFC return on July 12, 2026 lasted just 69 seconds before ending in disaster, as he suffered a serious left knee injury after throwing a jumping roundhouse kick against Max Holloway. McGregor, who had not fought since back-to-back losses to Dustin Poirier in 2021, buckled to the mat and the referee waved off the bout. He was booed by the Las Vegas crowd as he left the arena, with Holloway attempting to encourage the audience to show appreciation for the Irishman.
