Chijindu Ujah, who won a silver medal at the Tokyo Olympics as part of the British team in the men's 4x100 metres relay, has been suspended for a doping violation, the Athletics Integrity Unit announced Thursday.

The 27-year-old — along with his teammates Nethaneel Mitchell-Blake, Richard Kilty and Zharnel Hughes — could be stripped of their medal. The Canadian team — consisting of Aaron Brown, Brendon Rodney, Jerome Blake and anchored by Andre De Grasse — claimed bronze, while China finished in fourth.

According to the AIU, Ujah tested positive for S-23 — a selective androgen receptor modulator, which aids muscle building — and Ostarine, an anabolic agent designed to have similar effects to testosterone.

The AIU also announced that three other athletes tested positive for a banned substance at the Games and have been suspended, including middle-distance runner Sadik Mikhou of Bahrain, Georgian shot putter Benik Abramyan and Kenyan sprinter Mark Otieno Odhiambo.

"The AIU now awaits the conclusion of the ITA proceedings against the above athletes, which will determine whether any anti-doping rule violations have been committed and what consequences (if any) should be imposed in relation to the Olympic Games," the organization said in a press release.

"Any consequences beyond the Olympic Games to be imposed upon the athletes under the World Athletics Anti-Doping Rules will be determined following the conclusion of the ITA proceedings."
