Conor McGregor confirmed he tore his anterior cruciate ligament and meniscus during his defeat to Max Holloway, the Irish fighter said in a statement posted to Instagram on Sunday. The injuries will require surgery and lengthy rehabilitation.

McGregor, 37, lost to Holloway in his latest attempt to return to elite competition after years disrupted by injury. He previously fractured his left tibia during a 2021 loss to Dustin Poirier, an injury that sidelined him for extended periods.

The former two-division UFC champion did not provide a timeline for surgery or return in his statement. The setback deepens uncertainty over whether McGregor will fight again inside the Octagon, given his age and accumulated injury history.

UFC president Dana White has not confirmed any rescheduled plans involving McGregor, and the promotion has made no formal announcement regarding his status. The injury removes one of the sport's biggest commercial draws from the schedule for the foreseeable future.

McGregor, whose last sustained run of activity came before 2021, has repeatedly stated his intention to return to the top of the lightweight and welterweight divisions despite the physical toll of recent years.
