Aftermath
On July 19, 2024, UFC announced that Irina Alekseeva – who fought at this event – had tested positive for testosterone of exogenous origin already in April, but UFC's antidoping partner at the time, USADA, failed to inform both UFC and Alekseeva in timely fashion. If the information had arrived prior to the event, Alekseeva would not have had permission to compete. Subsequent samples provided by Alekseeva were negative, but she was banned from competition by CSAD (Combat Sports Anti-Doping) for 12 months nevertheless, making her eligible to return to competition on October 15, 2024.[20]
