# Athletics: The silver medal winner in the 200-metres at the world championships in 2023, American Erriyon Knighton, received a four-year ban for doping. The 21-year-old was charged in May last year after an out-of-competition test revealed the presence of a prohibited anabolic steroid. The US Anti-doping Agency wanted to sanction him, but an arbitration tribunal found he bore no fault or negligence. World Athletics and the World Anti-doping Agency’s appeal to the Court of Arbitration for Sport was now upheld.
