May 16 : Former two-weight mixed martial arts world champion Conor McGregor will make his long-awaited return to the UFC octagon on July 11 in Las Vegas, UFC President Dana White announced during Saturday night's UFC card. The Irishman, who has not fought since breaking his leg against Dustin Poirier in July 2021, faces Hawaiian Max Holloway in the main event at UFC 329 in the T-Mobile Arena in Las Vegas, with the contest taking place at lightweight/welterweight.With his flashy striking style and penchant for entertaining and offensive trash-talk, McGregor debuted with the promotion in 2013 and quickly became the biggest star in the sport, adding the UFC lightweight title to his featherweight crown in 2016 to become the first athlete to hold two UFC belts simultaneously.McGregor's brash manner proved a huge hit with fans around the world, and he was instrumental in helping the sport of MMA, which was once famously derided by U.S. Senator John McCain as "human cockfighting", to gain mainstream acceptance.

The ban was back-dated and expired in March. If McGregor does fight Holloway on July 11, it will be five years and one day since his broken leg against Poirier.
