The Nevada State Athletic Commission is now expected to impose a medical suspension on the Irishman as a consequence of the injury, with a six-month ban inevitable.But McGregor may now retire from the sport having suffered yet another injury. And he took to social media to explain he was not carrying a knock. "My head gasket is gone," he said. "Destroyed. I had no injury / injuries going into the fight. I was throwing kicks, planted and jumping, all throughout camp as well as backstage before the fight. This came out of nowhere. I am beyond dark here. I can only describe it as hell."‌UFC CEO Dana White updated fans when he said: "I was expecting at least a one round war... We're assuming blown ACL. The doctor's think the same thing too. In the opening exchanges of the UFC 329 main event, McGregor threw a kick with his left leg, only to appear to cause serious damage to his right knee in the process.The fight was officially stopped at one minute and nine seconds, leaving McGregor floored on the canvas, as Holloway wasted no time in calling for a rematch.This marked the Dublin fighter's long-anticipated comeback to the octagon following the devastating leg break he suffered against Dustin Poirier five years ago in July 2021. McGregor had been desperate to get the better of Holloway for a second time, 13 years on from their featherweight encounter in Boston.Despite pledging to bulldoze his way through Holloway, the contest barely got off the ground, raising serious doubts over whether the former two-weight world champion will ever compete inside the cage again.Choose Daily Mirror as a 'Preferred Source' on Google News for quick access to the news you value.‌Conor McGregorUFC
