British sprinter Chijindu Ujah or C.J. Ujah has been suspended from competition after testing positive for a banned substance on Thursday (12).
Ujah, 27, was part of the Great Britain men's 4x100 m relay team which won silver at the Tokyo 2020 Olympics ended recently.
A UK Athletics spokesperson has said the governing body does not comment on ongoing processes.
Ujah, who has yet to comment, won the 100 m at the British Championships too, held in June. Britain's men's quartet missed out on the 4x100 m gold in Tokyo by just a hundredth of a second.
Ujah ran the opening leg as 'anchor runner' Nethaneel Mitchell-Blake was overhauled on the line by Italy's Filippo Tortu.
Whole team strip of the medals
World Athletics Anti-Doping rules state that in instances where an athlete who has committed an 'ADRV' (Anti-Doping Rules Violation) competed as a member of a relay team, "the relay team shall be automatically disqualified from the event in question, with all resulting consequences for the relay team, including the forfeiture of all titles, awards, medals, points, and prize and appearance money".
Enobosarm, or Ostarine, is listed as an anabolic agent --banned at all times-- in the World Anti-Doping Agency's list of prohibited substances.
The UK Anti-Doping (Ukad) website said it has "similar effects to testosterone".
S23 is a Selective Androgen Receptor Modulator (Sarm), which, according to the United States Anti-Doping Agency (Usada) "have similar anabolic properties to anabolic steroids".
Court of Arbitration for Sport will consider
Ujah can request analysis of the B-sample --kept for storage while the A-sample is analysed-- and should that confirm the Adverse Analytical Finding (AAF), the case will be referred to the Anti-Doping Division of the Court of Arbitration for Sport (Cas ADD), confirmed BBC.
In turn, the International Testing Agency (ITA) said: "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 m relay results of the British team".
Three more Tokyo athletes banned
Three other athletes have been suspended after tests carried out during the Tokyo Olympics.
They are Bahrain's 1500 m runner Sadik Mikhou, shot putter Benik Abramyan of Georgia, and Kenyan sprinter Mark Otieno Odhiambo.
