Canadian 4x100m team upgraded to silver following British team’s positive drug test

The British team was provisionally suspended after CJ Ujah's positive test for two banned substances in the wake of their silver medal performance in Tokyo

Canada’s 4x100m men’s relay team, which won bronze at the Tokyo 2020 Olympics, has been upgraded to second place following the disqualification of the team from Great Britain on a doping violation. The AIU investigation into a positive test by Team GB member Chijindu (CJ) Ujah began after the Games, on Aug. 12, and concluded with the announcement by the Court of Arbitration for Sport on Friday. This means that Aaron Brown, Jerome Blake, Brendon Rodney and Andre De Grasse’s medals will be upgraded to silver. And the Chinese team, which finished fourth, will be upgraded to bronze.

Olympic relay silver medallist’s B-sample tests positive

Ujah’s teammates, who have been stripped of their medals, are Zharnel Hughes, Richard Kilty and Nethaneel Mitchell-Blake. In a response to the announcement, Ujah tweeted that he “unknowingly consumed a contaminated supplement,” which was the reason for the positive test. He apologized to the team and to UK Athletics, saying the consequences of his mistake is something he will “regret for the rest of his life.”

According to the Athletics Integrity Unit press release issued when the investigation began, Ujah tested positive for two substances: ostarine and S-23. Neither is a steroid; they are selective androgen receptor modulators (SARMs), which have similar properties to anabolic steroids, but with reduced androgenic properties.

The 4x100m relay was won by the team from Italy, featuring 100m gold medallist Marcell Lamont Jacobs. In addition to the relay, De Grasse won gold in the 200m and bronze in the 100m.
