Conor McGregor’s long-awaited return to the UFC ended almost immediately when he appeared to suffer another serious knee injury during his fight with Max Holloway. According to the article, McGregor started aggressively but slipped while throwing early kicks, suggesting something was wrong, and the bout was stopped less than two minutes in. The incident matters because it raises fresh doubts about the future of one of MMA’s biggest stars after five years away from the Octagon.

The report says McGregor attempted a running kick and then a head kick, but slipped on both occasions before later grabbing at his right leg again. Referee Mike Beltran halted the contest shortly afterwards, and Fox News notes that UFC president Dana White believed McGregor may have torn his ACL. The headline also refers to a three-word promise about McGregor’s UFC career, though the supplied text mainly focuses on the injury and the abrupt end to his comeback fight.
