Conor McGregor said Monday that he will undergo surgery after injuring his knee against Max Holloway at UFC 329.
The former two-division champion suffered the injury just seconds into his comeback bout this past weekend in Las Vegas, officially losing via first-round TKO.
McGregor reiterated that he plans to recover and then return to the Octagon to complete his contract.
"All things are possible for me because I am a believer!" McGregor wrote on Instagram. "Surgery. Prehab. Return to martial arts practice. Go again. Final fight of the contract."
The extent of McGregor's injury is unknown, though UFC CEO Dana White said doctors believe he tore his ACL.
It was McGregor's first fight in five years, ending the longest layoff of his career. The 37-year-old Irishman hadn't fought since breaking his leg against Dustin Poirier in July 2021.
In the immediate aftermath of UFC 329, McGregor denied having a pre-existing injury and said he wouldn't be "deterred" by this latest setback.
