Great Britain will be stripped of their Tokyo 2020 men’s 4×100 metres relay silver medal after CJ Ujah’s B sample confirmed his positive test.
The International Testing Agency (ITA) announced last month that Ujah had tested positive for two prohibited substances.
According to the AIU, Ujah, who is the British champion over 100m, tested positive for ostarine and S-23, both of which are listed as prohibited substances by the World Anti-Doping Agency.
Ujah requested a B-sample analysis be carried out, which the ITA says has confirmed the initial test results.
The case will now be referred to the Court of Arbitration for Sport Anti-Doping Division on 8 September 2021..
“The ITA confirms that as per the athlete’s request, the B-sample analysis was carried out by the WADA-accredited laboratory of Tokyo on 19 August 2021 and the procedure confirmed the result of the A-sample,” an ITA statement read.
“The Cas ADD will consider the matter of the finding of an Anti-Doping Rule Violation [ADRV] and the disqualification of the men’s 4 x 100 relay results of the British team”.
Ujah, along with Kilty, Hughes and Mitchell-Blake, only narrowly missed out on winning gold in Tokyo.
The quartet were leading going into the final 100m but unable to hold off the Italian challenge as anchor runner Mitchell-Blake was headed on the line by Filippo Tortu.
Team GB missed out on gold by just a hundredth of a second.
