American sprinter Sha’Carri Richardson has criticised the Court of Arbitration for Sport’s decision to allow Kamila Valieva to continue competing at the Winter Olympics in Beijing.
The 15-year-old figure skater helped her Russian Olympic Committee team win gold in the team event last week, but a sample analysed by the World Anti-Doping Agency found that she had tested positive for the banned substance trimetazidine at the Russian Figure Skating Championships on Christmas Day.
