Sprinter Sha’Carri Richardson was not on the U.S. Olympic track and field roster announced Tuesday.
Richardson was retroactively disqualified from the Olympic Trials, where she won the 100m on June 19, because she tested positive for marijuana after the final. Marijuana is banned in competition by the World Anti-Doping Agency.
Richardson’s one-month ban began June 28, meaning it will expire during the Tokyo Games but before track and field competition starts.
Richardson can’t compete in the 100m at the Olympics because of her Trials DQ, but USA Track and Field’s athlete selection policy did not make clear whether an athlete in Richardson’s situation would also be excluded from 4x100m relay pool availability.
