Former UFC double champion Irishman Conor McGregor has officially returned to the American Anti-Doping Agency (USADA) testing pool.
McGregor's name appears on the organization's website on an updated testing list, meaning he has submitted samples for analysis for the first time since 2021.
McGregor, 35, last fought against Dustin Poirier in July 2021 at UFC 264. In this confrontation Conor suffered a defeat by technical knockout after breaking his leg. He has 22 wins and six losses on his record.
