Olympic sprinter Erriyon Knighton gets 4-year ban for positive test for anabolic steroid

Two-time Olympic finalist Erriyon Knighton was banned for four years on Friday in a doping case of an anabolic steroid that rules 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 filed after Knighton was cleared by a tribunal in the U.S. that accepted he was contaminated by eating meat. WADA and the Athletics Integrity Unit argued the evidence that had been presented was statistically impossible and asked for a maximum four-year ban, the court said.
