Three-times U.S. 200 metres champion Wallace Spearmon Jr. has been suspended for three months after testing positive for a banned substance, the U.S. Anti-Doping Agency (USADA) said on Friday.
Spearmon, 29, tested positive at a meeting in Edmonton, Canada in July for methylprednisolone, a banned substance contained in a prescribed medication the twice Olympian was taking under the care of a physician, USADA said.
