Team GB have been stripped of their men's 4x100m relay Olympic silver medals from last year's Games in Tokyo by the Court of Arbitration for Sport (CAS), following CJ Ujah's doping violation.
Ujah was provisionally suspended for the violation after winning silver alongside his relay teammates at last summer's Games.
This came after the sprinter tested positive for banned substances known as SARMs (Selective Androgen Receptor Modulators) and Ostarine, an anabolic agent, which is used to help athletes illegally build muscle.
