Man up, Collins tells banned Powell

Asafa Powell cannot use ignorance as an excuse for his 18-month drug ban, says former 100m world champion Kim Collins. Jamaica's Powell, 30, was punished at a hearing on Thursday after testing positive for the stimulant oxilofrine. Former 100m world record holder Powell said he took the substance unwittingly in a supplement given by his coach. "If you say you trust people, and that's what happens, you're just as bad as them," Collins told BBC Sport, adding that cheats nd to "man up".
