Conor McGregor’s return at UFC 329 on July 11, 2026 against Max Holloway lasted only a few seconds before a left knee ACL and meniscus injury sidelined him, making him ineligible to continue. Dana White said McGregor would be out for about a year and require knee surgery followed by extensive rehab, though his timelines have since varied. White’s communications have been inconsistent, shifting between a lengthy comeback and uncertainty about a precise return date. McGregor has kept fans engaged with social-media updates, including leg-extension workouts as he documents his recovery and the possibility of a return by summer 2027. Analysts and former fighters have weighed in on the potential for a comeback, highlighting McGregor’s drive and the resources available to him. There remains ambiguity about whether recent training clips reflect current plans or older footage, with no definitive comeback timetable announced.
