Conor McGregor back in testing pool but USADA says it’s splitting with UFC

COLORADO SPRINGS, Colo. — Former UFC champion Conor McGregor’s return to action helped trigger a split between the league and the U.S. Anti-Doping Agency, which has been testing the league’s mixed-martial arts fighters for the past eight years. McGregor announced on social media this week that he is returning to the USADA testing pool — a step the 35-year-old fighter must take before returning to the octagon for the first time since suffering a leg injury in July 2021. USADA requires any athlete who has been out of action to submit to six months’ of testing and provide at least two negative tests before returning. In a statement Wednesday, USADA CEO Travis Tygart said the agency had been “clear and firm” about those requirements applying to McGregor, who during the summer went on social media and said that because of the testing rules “I feel like I’m being kept from my livelihood, and I’ve been feeling this for years.” “Unfortunately, we do not currently know whether the UFC will ultimately honor the six-month or longer requirement because, as of January 1, 2024, USADA will no longer be involved with the UFC Anti-Doping Program,” Tygart said.
