UEFA says it banned Dinamo Zagreb midfielder Arijan Ademi for four years after he tested positive for doping at a Champions League match. Ademi tested positive for a substance that has not been identified after playing in Dinamo's 2-1 win against Arsenal on Sept. 16. It will not affect the result as UEFA rules allow it to stand if only one player in a team is caught doping. The 24-year-old Ademi has denied deliberately doping and claimed he took a dietary supplement that was contaminated. Dinamo said in a statement late Friday that it would appeal, AP reported.
