Former world record holder to appeal 18-month suspension for doping

Jamaican sprinter Asafa Powell, the former 100m world record holder, slammed the 18-month doping ban meted out to him on Thursday calling it "unfair" and "unjust".

"This ruling is not only unfair, it is patently unjust. Panels such as these, I understood, were assembled to allow athletes who, consciously or unconsciously come into conflict with the rules of sport, a chance at equitable redemption," Powell said in a statement posted on his website.
