Conor McGregor surgery plans are now official. Two days after his knee injury at UFC 329, McGregor confirmed on social media that he will operate on the joint before completing his UFC contract. The update settles one question and opens several bigger ones about his timeline.
What McGregor Actually Said
McGregor posted the update on Instagram and X on Monday, two days removed from the loss. His message was short and direct. “Surgery. Prehab. Return to martial arts practice. Go again. Final fight of the contract,” he wrote.
That last line matters most. McGregor still has two fights left on his current UFC deal. He is not walking away from either of them. He is telling fans the surgery is step one in a longer plan that ends with him back in the octagon.
The Injury That Forced This Decision
McGregor’s right knee buckled seconds into his rematch with Max Holloway at UFC 329. He landed a flying kick awkwardly and could not plant his lead leg after that. Referee Mike Beltran stopped the fight at 1:09 of round one, handing Holloway a TKO win.
McGregor has not shared an official diagnosis yet. He has, however, described the internal damage in blunt terms. He called it his “head gasket,” saying it was destroyed. That phrasing suggests structural damage, not a minor sprain, even without a formal medical report.
McGregor Denies A Pre-Existing Injury
Online criticism grew fast after the stoppage, with fans and insiders questioning if McGregor entered hurt. McGregor rejected that directly in his post. He said he threw kicks, planted, and jumped normally through camp and even backstage minutes before the walkout.
This detail carries real weight for his medical timeline. If the injury happened live in the cage, as McGregor insists, the surgical approach and recovery plan depend entirely on fresh damage. A pre-existing issue would change how doctors treat the joint and how long rehab takes.
The Bigger Picture: His Contract And Free Agency
McGregor entered UFC 329 with two fights remaining on his deal. Before the Holloway rematch, he and UFC officials had already discussed a rough return window of April 2027 for the fight after this one. That plan now depends entirely on how this surgery and rehab go.
McGregor has also confirmed he wants to test free agency once his contract ends. He has called himself the highest-paid fighter in the sport, and he wants a deal that reflects that once he is a free agent. Surgery outcomes now sit at the center of that entire negotiation.
Why This Recovery Is Different From His Past Injuries
McGregor tore his ACL in this same knee back in 2013. He broke his tibia in the other leg against Dustin Poirier in 2021, which cost him three years away from competition. Two serious leg injuries by age 37 is a pattern most coverage treats as a footnote instead of the headline.
A body that has already absorbed two career-altering leg injuries does not heal the same way a fresh one does. Scar tissue, altered movement patterns, and years of compensation add real risk to any recovery timeline, no matter how disciplined the rehab plan looks on paper.
What Comes Next
Surgery details, including the exact procedure and surgeon, have not been released. Once McGregor has the operation, his team will set a rehab timeline based on the actual damage found during the procedure. That single detail will decide if 2027 is realistic or optimistic.

The Bottom Line
Conor McGregor surgery is confirmed, and his plan is clear. He wants to fix the knee, complete his final two fights, and test free agency once his UFC contract ends. The real story now is not whether he returns. It is whether a body that has already taken this much damage can hold up long enough to get there.
For the latest confirmed updates on his surgery date and recovery, ESPN MMA has tracked this story closely since fight night. Until McGregor’s team names a surgeon and procedure, every recovery estimate stays an educated guess.
