Powell trainer denies wrongdoing

Asafa Powell’s trainer has insisted he is not to blame for the Jamaican sprinter’s positive drugs test and claims he is being made a scapegoat.

Chris Xuereb, a Canadian, has had the finger of blame pointed at him by Powell’s agent Paul Doyle after the sprinter and three-times Olympic medallist Sherone Simpson, both tested positive for the same banned stimulant oxilofrine.
