Great Britain's men's 4×100 meter relay team was stripped of its silver medals from the Tokyo Olympics on Friday after a sprinter failed a drug test.
Sprinter CJ Ujah tested positive for a banned substance after the Games in August, according to a statement from the Court of Arbitration for Sports.
Ujah, who was part of silver medal-winning relay team and and also competed 100-meter sprint at the Olympics, was ordered by the CAS to forfeit the medal he won at the Tokyo Games.
His 4×100 relay teammates — Nethaneel Mitchell-Blake, Richard Kilty, and Zharnel Hughes — were also stripped of their silver medals for the event, the CAS said.
CAS said in its statement that Ujah told officials that 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 Brit tested positive in August 2021 for two muscle building substances, Ostarine and S-2. The former is not approved for human consumption in any country.
Team GB finished second to Italy in the race, with Italian sprinter Lamont Jacobs securing his second gold of the Tokyo Olympics. Jacobs also won the individual 100 meter sprint in a rare athletic gold for Italy.
Jacobs' victories were not without controversy, however, after it emerged that his former nutritionist, bodybuilder Giacomo Spazzini, had been implicated in a widescale investigation into the illegal distribution of anabolic steroids in Italy.
There is no suggestion that Jacobs has been involved in doping and he has never failed a drugs test.
However, after Ujah's positive test became public in August 2021, the Italian seemed to revel in the news.
"After seeing the Ujah investigation I would say that perhaps it is better to look into your own house first and then attack others. It makes me smile," Jacobs told Italian media outlet Tuttosport at the time.
"It makes me smile, thinking of those people who spoke without thinking about what they were saying, who must now look to their own home instead," he added in an interview with Rai, per Reuters.
