Great Britain stripped of Tokyo Games men's relay silver

Great Britain have been stripped of their silver medal in the 4x100 metre relay at last summer's Tokyo Olympics after team member Chijindu Ujah was found to have committed a doping violation.

The British team just lost out to Italy for the gold medal in Japan, with Ujah testing positive for the prohibited substances ostarine and S-23 after the race on 6 August.

A statement issued by the Anti-Doping Division of the Court of Arbitration for Sport (CAS ADD) on Friday said Ujah did not challenge the anti-doping rule violation, but argued he had "not knowingly or intentionally doped, suggesting that the source of the prohibited substances could have been the ingestion of a contaminated supplement".

The statement added: "The CAS ADD sole arbitrator issued the present decision in which she determined, to her comfortable satisfaction, that an anti-doping rule violation had been committed."
