Kerley won 100m gold at the 2022 World Championships, along with the men’s 4x100m titles in 2019 and 2023.<\/p>\n
He also made the 100m podium at the past two Olympic Games, winning silver at Tokyo 2020 and bronze at Paris 2024.<\/p>\n
“Given this level of experience and having been a member of the Testing Pool since 2017, the Tribunal said Kerley should have exercised more care,” an AIU statement stated.<\/p>\n
Head of the AIU Brett Clothier said: “Unfortunately, sophisticated doping substances may only be detectable within an athlete’s sample for a few days or even hours after administration. <\/p>\n
“Anti-doping organisations need to be able to test athletes without notice on the day and hour of our choosing, otherwise anti-doping programmes will not work, and dopers will easily avoid detection. Whereabouts rules are therefore fundamental to the integrity of sport and must be respected.<\/p>\n
“The AIU will continue to strictly enforce whereabouts requirements to protect the right of all athletes to clean competition.”<\/p>\n
Kerley, who last competed at the Grand Sprint Series in Norwalk, California in July 2025 became the first track athlete and American male to sign up to the controversial Enhanced Games<\/a> in September.<\/p>\n He did not dispute his whereabouts failure on 13 June – but blamed technical issues with the United States Anti-Doping Agency (Usada) app for a missed test on 11 May, and the Doping Control Officer (DCO) for missed tests on 6 and 7 December.<\/p>\n This decision may be appealed to the Court of Arbitration for Sport (Cas).<\/p>\n<\/div>\n
