Conor McGregor has come back to UFC, as the Irish fighter announced his return during his presence at the O2 Arena in London to watch the boxing match between Anthony Joshua and Robert Helenius. 'The Notorious' (22-6) confirmed that he will fight in the UFC in December against Michael Chandler (23-8). Not only that, but Conor McGregor went even further as he found out that as early as 2024 he will step into the octagon twice more to first measure himself against Justin Gaethje and then close the trilogy against Nate Diaz. He even stated that Chandler next December and then Gaethje's BMF and then we'll do the Nate trilogy. Where has Conor McGregor been these days? McGregor has been sidelined since he suffered a horrific fracture against Dustin Poirier in 2021. Prior to his return to competition, 'The Notorious' had to undergo six months of anti-doping testing and have a minimum of at least two negative tests (more can be done, and they must all be negative) as McGregor was left out of the USADA testing pool that tracks all active athletes. Conor McGregor is stated to be an active athlete and he is officially registered n a competition or circuit in the United States does not leave the control group, but in McGregor's case, he did, as his inactivity was going to be long. McGregor along with Chandler who are going to lock horns, know each other very well, as they were the stars of the last edition of 'The Ultimate Fighter 31', the UFC reality show, which Chandler's team won. During this duel, McGregor already warned that he would fight again in December. For his part, the Irishman and Gaethje, a new BMF belt, got into a spat on Twitter in early August and included a "contract" in their discussions. Gaethje even shouted at McGregor that if he signed the contract or not, stating him as the big guy! He went from "I don't fight someone on steroids" to dropping that the UFC wanted to match them. The Irishman was quick to throw out a "signed."
