Conor McGregor has announced his retirement from fighting for the third time in four years. McGregor abruptly made his latest dubious declaration on his Twitter account, where the former two-division UFC champion also announced his retirement in 2016 and 2019. The 31-year-old McGregor revitalized his combat sports career in January with an impressive first-round stoppage of Donald “Cowboy” Cerrone at UFC 246. McGregor remains the UFC’s biggest star and biggest financial draw. UFC President Dana White has already said McGregor is next in line for a title shot at the winner of lightweight champion Khabib Nurmagomedov’s bout with Justin Gaethje this summer.
