Conor McGregor has revealed that he’s successfully undergone ACL surgery and is now looking to draw inspiration from some other UFC legends as he begins his long journey back to competing again.

“What’s up, folks?” McGregor said in a new video on social media. “‘The Mac’ is back, baby. Surgery was a success and now I’m on the road to recovery. That should tell you all you need to know about my mindset. Straight into surgery, knee repaired, and on the road. Let’s go.

“I want to give a shout-out to Dominick Cruz, who returned from multiple ACLs to recapture his bantamweight crown. Georges St-Pierre, multiple ACLs. I don’t know whether he returned after his second ACL, however he’s doing backflips and his movement is still stellar. Other notables in other sports, NFL, Tom Brady’s done it. Aaron [Rodgers] done it. These are my motivation here, especially the fighting boys.

“Unstoppable, baby. My mindset is unstoppable, unbreakable.”

This is McGregor’s second ACL surgery, with the first having also happened during a fight with Max Holloway all the way back in 2013, though on that occasion he was able to fight through it to still win by unanimous decision.

On that occasion McGregor didn’t compete again for 11 months afterwards, but that was 13 years ago, and given that he’s now 38-years-old it remains to be seen how long it’ll take him to recover from this serious injury.
