Chijindu Ujah, who competed in the 4x100m relay in Tokyo, has been provisionally suspended.
British sprinter Chijindu Ujah has been provisionally suspended for an anti‑doping violation after reportedly testing positive for two banned substances after winning a silver medal in the 4x100m relay at the Tokyo Olympics.
As a result of the suspension, the entire 4x100m Men’s relay team face having their medals stripped, which would give Canada the silver and bring China up to a bronze medal, The Guardian  reported.
If the suspension is upheld, it could represent one of the biggest scandals in British Olympic history, and Ujah could face a multi-year ban for the offence if he cannot satisfactorily explain why the substances were in his system.
A test on Ujah had shown the “presence/use of a prohibited substance (ostarine and S-23)”, according to the Athletics Integrity Unit.
These two substances are part of a new class of drugs called selective androgen receptor modulators (Sarm) which are touted as replicating the effects of testosterone, and both are banned.
“The result was reported by the Wada-accredited laboratory of Tokyo on 8 August 2021,” the International Testing Agency said. “The athlete has the right to request the analysis of the B-sample.
“If requested by the athlete and if the B-sample analysis confirms the adverse analytical finding… the case will be referred to the anti-doping division of the court of arbitration for sport for adjudication.
“It will consider the matter of the finding of an anti-doping rule violation and the disqualification of the men’s 4×100 relay results of the British team.”
None of the other Brits in the race have previously tested positive for a banned substance.
