"Surgery, rehab training, martial arts training. Then I'm back on track. Last fight on the contract," McGregor writes on X.
This weekend's fight against Max Holloway was stopped after just one minute and nine seconds after McGregor suffered a knee injury when attempting a roundhouse kick.
McGregor writes that he has not had problems with his knee before.
"I kicked, put my foot down and jumped - both during training camp and backstage before the fight. I had no injuries before the fight," he writes.
