AIU Files Appeal in Knighton Doping Offence

The Athletics Integrity Unit has launched an appeal after USA sprinter Erriyon Knighton was cleared over a doping offence allowing him to compete at the Paris 2024 Olympics.

The appeal has been lodged with the Court of Arbitration for Sport, Cas.

Knighton tested positive for trenbolone – a banned substance used for muscle growth – in March but avoided a ban following an independent arbitrator’s ruling.

The United States Anti-Doping Agency, Usada, said the independent arbitrator ruled he more than likely digested the banned substance by eating contaminated meat.

The 200-metres world silver medallist went on to compete at the Olympics and finished fourth in the men’s 200-metres final.
