Team GB 's 4x100m relay men's runners have been ordered to give back their medals from the Tokyo Olympics in the wake of the doping violation from CJ Ujah.
He ran the first leg of the final and helped the quartet to win silver as they narrowly missed out on the win to the Italian team. But he was provisionally suspended in the following days after a test showed the presence of two banned substances.
"I am not a cheat," Ujah declared at the time, adding that he "would never knowingly take a banned substance". But the Court of Arbitration for Sport (CAS) officially stripped the team of second place in February, after which he revealed he had "unknowingly consumed a contaminated supplement".
