Jamaican 400-metre runner Bobby-Gaye Wilkins has been banned for two years for using a performance-enhancing substance.
Warren Blake of the Jamaica Amateur Athletic Association says the athlete will be barred from competition until April 2012.
Wilkins tested positive for the banned substance andranine at the indoor world championships in Doha, Qatar, in March. She was a member of the Jamaican 4x400 relay team that won a bronze medal at the tournament.
