Britain’s 4x100m relay team has surrendered their silver medals from the Tokyo Olympics after sprinter Chijindu Ujah tested positive for doping. The British had finished second behind Italy in Tokyo. Silver now goes to the third-placed Canadians, bronze to China.
Traces of the banned substances ostarine and S-23, which promote muscle growth, were found in 28-year-old Ujah shortly after last summer’s games. Ujah did not contest the anti-doping rule violation, arguing that the positive test was caused by ingestion of a contaminated drug. The Court of Arbitration for Sport CAS ordered the return of the medals.
