Conor McGregor claims he's "feeling tremendous" after having surgery on his broken leg which he sustained during his UFC 264 defeat to Dustin Poirier on Sunday.
He claimed that Dustin Poirier's win in their fight was "illegitimate" due to the injury.
The Dubliner was rushed to hospital following the defeat in the early hours of Sunday morning.
The Notorious broke his lower leg in the main event bout, with Poirier declared the winner via TKO following a doctor's stoppage.
In a post on social media, McGregor said that he's expecting to spend the next six weeks on crutches.
"What's up fight fans, The Notorious here. Just out of the surgery room, everything went to plan and everything went perfect. I'm feeling tremendous, we got six weeks on a crutch now and then we begin to build back," he said.
After seemingly hearing McGregor's leg crack during one exchange, Poirier took his opponent to the ground, where he dominated before the fighters returned to their feet.
Both swung and missed as McGregor stepped back before his leg collapsed beneath him.
The Dubliner somehow survived until the end of the round when the bout was stopped.
Later in the post, The Notorious thanked all his fans for their support during the fight before taunting Poirier for his "illegitimate" win and saying the American had "done nothing in there."
"I want to thank all the fans around the world for your messages of support, I hope you all enjoyed the show. I want to thank all the fans in attendance at T Mobile Arena - 21,800 fans in attendance, the place was absolutely electric.
"It was a hell of a first-round, it would have been nice to get into that second round and then to see what's what, but it is what it is. That's the nature of the business, a clean break of the tibia. It was not to be," he said.
McGregor adds: "Dustin, you can celebrate that illegitimate win all you want but you've done nothing in there. That second round would have shown all. Onwards and upwards we go, team. We just ourselves off, we build ourselves back and we come back better than ever. Let's go, team."
