Russia's wrestling team may not compete at the Rio Olympics after recording a number of positive doping results. The head of the Russian Wrestling Federation says the violations were detected during an internal investigation. A report by the World Anti-Doping Agency (WADA) exposed widespread cheating and corruption in Russian athletics last year. Russia’s athletes are currently suspended from international competition, but the country is trying to get the ban overturned in time for the Rio Olympics in August.
