Conor McGregor Undergoes Successful Knee Surgery, Targets 2027 Return

Mixed martial arts superstar Conor McGregorPlayer·Conor McGregor has successfully completed surgery to address a significant knee injury, a development that offers a clear path forward for the former two-division UFCCompetition·UFC champion. The procedure, which repaired a torn anterior cruciate ligament (ACL) and meniscus in his right knee, was confirmed by McGregor himself on Wednesday, following the setback that abruptly ended his highly anticipated return to the octagon.

“Surgery went excellent! I am confident!”— Conor McGregor.

The injury occurred during McGregor's welterweight bout against Max HollowayPlayer·Max Holloway at UFC 329Competition·UFC 329 on July 11, 2026. Just 1 minute and 9 seconds into the first round, McGregor landed an awkward spinning kick, resulting in a compromised landing that immediately affected his knee. Despite his attempts to continue, the injury rendered him unable to compete, leading the referee to halt the contest and declare a TKO victory for Holloway.

This unfortunate incident marked a swift end to McGregor's comeback, which followed a five-year hiatus from active competition. His previous absence was partly due to a broken leg sustained in an earlier UFCCompetition·UFC bout and an 18-month anti-doping sanction that concluded in March 2026. The recent loss to Holloway was McGregor's third consecutive defeat, extending his winless streak since January 2020 and bringing his professional MMA record to 22-7-0.

Medical experts typically project a recovery period of 9 to 12 months for an ACL tear, suggesting a substantial time away from competitive fighting for McGregor. This is not the first time the Irish fighter has faced such a challenge; he underwent surgery for a similar ACL injury in 2013 after his initial fight against Max HollowayPlayer·Max Holloway. On that occasion, he managed to complete the fight, securing a unanimous decision victory before his subsequent recovery.

Looking ahead, McGregor has already set his sights on a return to the cage, targeting the International Fight WeekCompetition·International Fight Week in 2027 as his planned comeback date. He has one fight remaining on his current UFCCompetition·UFC contract and has expressed a clear intention to fulfill this obligation, referring to it as "The Last Dance," before potentially exploring opportunities outside the organization. The UFCCompetition·UFC will await his full medical clearance before scheduling any future bouts, ensuring a cautious approach to his return to elite competition.
