Wallace Spearmon accepts three-month doping ban
American sprinter Wallace Spearmon has accepted a three-month ban by the United States Anti-Doping Agency (USADA) after testing positive for a banned substance.
The 200m specialist, 29, returned a positive test for methylprednisolone after a meeting in Edmonton in July.
USADA accepted his explanation that he was taking the medicine in "a therapeutic dose".
But it said he failed to apply for a therapeutic use exemption beforehand.
His three-month ban was backdated to start on 27 August.
The substance is prohibited in competition and classified as a specified substance, meaning its presence can come with a reduced sanction.
Spearmon, who is the seventh fastest man over 200m in history with a best of 19.65 seconds, won gold in the 4x100m relay in Osaka in 2007 and silver in the 200m in 2005.
