LONDON—Britain’s men’s 4x100m relay team have been told to hand back their Tokyo 2020 silver medals after Chijindu Ujah’s doping violation, the British Olympic Association (BOA) said on Thursday.
Ujah and team mates Zharnel Hughes, Richard Kilty, and Nethaneel Mitchell-Blake finished second behind Italy last August but were stripped of the silver in February after a Court of Arbitration for Sport (CAS) ruling.
