At T-Mobile Arena in Las Vegas on July 11, 2026, Conor McGregor faced Max Holloway in the basic event of UFC 329, returning to the UFC octagon for the first time since his trilogy fight with Dustin Poirier at UFC 264 in July 2021. The bout ended 1 minute 9 seconds into the first round after McGregor sustained a knee injury and could not continue. Holloway was awarded a technical-knockout victory.
That 2021 fight, also held at T-Mobile Arena, ended with McGregor suffering fractures to his tibia and fibula. He needed surgery and a lengthy rehabilitation. His return came after more than five years away from competition. The UFC 329 injury involved his right knee’s ACL and meniscus, and McGregor underwent surgery in August. The two serious injuries mark distinct chapters in the extended recovery that has shaped his return to competition.
McGregor’s longtime training partner Dillon Danis described his rehabilitation and state of mind in comments reported by Mundo Deportivo: “He’s much better mentally now. He has a nurse caring for him 24 hours a day. He’s doing all the exercises.” Danis also said McGregor had isolated himself in Los Angeles to focus on his knee. McGregor has one UFC fight remaining on his contract, but no date or opponent has been announced for another appearance. He has floated a possible return during International Fight Week 2027, though no booking has been confirmed.
Holloway entered the rematch with a reported professional record of 28-9 and a UFC record of 24-9. He had previously fought McGregor in 2013, when McGregor won their featherweight contest. For UFC 329, Holloway moved up to 170 pounds. The victory was reported as his 28th professional win and his first over McGregor. The bout also added to his standing among fighters with UFC victories across three weight classes, spanning featherweight through welterweight.
McGregor’s earlier achievements remain basic to the attention surrounding his career: he knocked out José Aldo in 13 seconds in 2015 and became the UFC’s first simultaneous two-division champion in 2016. His long layoff and previous leg fracture made the UFC 329 comeback a major test. The knee injury cut it short after 69 seconds. Holloway has said he would be willing to wait for McGregor, leaving open the possibility of a rematch without making it a scheduled fight.
UFC 329’s official weigh-in confirmed McGregor and Holloway for the basic event, as detailed in recent coverage of the weigh-in proceedings. McGregor’s return brought renewed attention to his commercial and cultural influence on the sport. The result also showed the physical uncertainty elite fighters face after a prolonged absence and serious injury.
