He hasn’t fought in five years. Listen, I haven’t seen the results of the medical scans or anything they’ve done, but if it’s a torn ACL, after being away for five years, if it’s an ACL tear, I mean, that’s another year. The guy’s done. He’s done if he has a torn ACL.””He’s done. He’s done. He’s not going to be the same, but I do think he comes back. He’s got one fight left on his contract. I think he makes that walk. I don’t think he’s going to be the same. I don’t think the excitement and the expectations are going to be the same ever again.”Conor McGregor has made his intentions clear on returning to the UFC once his recovery is complete.
