Kingston, Jamaica: Backup doping tests have come back positive for former 100-meter world record-holder Asafa Powell, teammate Sherone Simpson and three other island athletes.
The Jamaica Anti-Doping Commission said the athletes' second samples were tested at a Montreal lab accredited by the World Anti-Doping Agency. It says all five athletes have been notified and the findings will be passed on to the Jamaican Anti-Doping Disciplinary Panel so hearings can be scheduled.
Paul Doyle, the agent for Powell and Simpson, did not immediately respond to a Friday email seeking comment. The athletes and their agent have focused on a new physical trainer, Christopher Xuereb of Canada, saying supplements he provided caused the positive tests.
