KINGSTON (AP):
Justin Gatlin's coach believes his sprinter was set up, and he knows who did it.
Gatlin, the 100-metre world record holder, has tested positive for doping and faces a lifetime ban from athletics because it is his second offense.
But Trevor Graham, Gatlin's coach, told a Jamaican television station that the American sprinter was "sabotaged".
"We are 100 per cent sure who it is," Graham said Saturday. "The individual that did it, it's an individual that we fired and we went back and hired ... he came to the Kansas relay and was (upset) with Justin.
"We are trying to go after the individual. Hopefully we can prove our case, but we know who the person is and how it got into his system," Graham added.
Graham has coached several athletes who have been involved in doping scandals, including former 100 record holder Tim Montgomery and triple Olympic gold medallist Marion Jones.
