The IAAF has received the athlete’s explanation for testing positive for modafinil at the World Championships in Paris last month and it has not been accepted.
In accordance with the usual disciplinary procedures under IAAF Rules, the matter is now referred to its Member Federation, USA Track and Field, for a hearing on a date to be agreed with the athlete. USATF delegates responsibility for the conduct of disciplinary hearings in doping cases to the United States Anti-Doping Agency, USADA.
The IAAF has already announced that, if it is confirmed after a hearing that the athlete has committed a doping offence, the proper sanction under IAAF Rules will be a public warning and disqualification from the competition concerned.
The athlete is not suspended pending her hearing before USADA.
