Former 100m world record holder Asafa Powell has received an 18-month ban for a positive doping test which he failed last year.
Powell, 31, did not take part in the 2013 World Championships in Moscow when he was flagged up on the system for the substance oxilofrine.
The test came back positive after the sprinter had competed in the Jamaican national trials last year and he was sanctioned by the Jamaican anti-doping disciplinary panel.
The Jamaican's ban has been backdated to June 21 2013 and will end in December 2014, giving him a chance to return ahead of the World Championships in China next year.
On Tuesday, Powell's training partner Sherone Simpson was also handed an 18-month ban for taking the same substance.
Simpson, who won a 100m silver medal at the Beijing Olympics blamed coach Christopher Xuereb for providing her with the supplements.
She said she had researched the "Epiphany D1'' supplement for up to 14 hours online before taking it but that excuse was deemed not good enough.
Tyson Gay, second-fastest man over 100m is currently awaiting his verdict after he failed a positive test for a banned steroid after the American Championships in May last year.
Gay, 31, who admitted he put his trust in someone else and has no excuses, will not retire and will look to return to action once the decision is made on his immediate future.
