German long jumper Kofi Amoah Prah, who was fifth at the 2000 Sydney Olympics, has been banned for two years after a positive test for cocaine.

The German Athletic Federation said Friday that Prah, who competed for LG Nike Berlin, tested positive for cocaine and Methylecgonine, a metabolite of cocaine, at the German championships on July 5.

The 33-year-old Ghana-born athlete, a silver medallist at the 1992 European indoor championships, announced his retirement on August 31 after receiving confirmation of the positive test.
