USA sprinter Knighton handed four-year doping ban

Erriyon Knighton won 200m silver at the 2023 World Championships in Hungary

United States sprinter Erriyon Knighton has been handed a four-year ban after the Court of Arbitration for Sport partially upheld appeals from World Athletics and the World Anti-Doping Agency against a decision not to suspend him.

The 21-year-old tested positive for trenbolone – a banned substance used for muscle growth – in March 2024.

He avoided a ban following an independent arbitrator's ruling and was cleared to compete at the 2024 Olympics, but is now banned with immediate effect.

Knighton, who finished fourth in the 200m in Paris last summer, was not selected in the USA team for the World Championships, which take place from 13-21 September in Tokyo, Japan.

U.S. sprinter Knighton banned, out of L.A. Games

GENEVA — Two-time Olympic finalist Erriyon Knighton was banned for four years on Friday in a doping case that ruled the 21-year-old United States sprinter out of the 2028 Los Angeles Games.

The Court of Arbitration for Sport said its judges upheld separate appeals by the World Anti-Doping Agency and track and field investigators, who filed after Knighton was cleared by a U.S. tribunal of testing positive for an anabolic steroid. The tribunal accepted he was contaminated by eating meat.

WADA and the Athletics Integrity Unit argued that the evidence that was presented to exonerate Knighton was statistically impossible and asked for a maximum four-year ban, the court said.
