Overview

• World Athletics and WADA won their appeals in part, leading the Court of Arbitration for Sport to impose the maximum sanction.
• The ban takes effect immediately with credit for a prior provisional suspension and runs to early July 2028, days before the Los Angeles Olympics open.
• CAS found no evidence that imported oxtail would contain trenbolone residues at levels capable of producing Knighton’s positive test.
• Retroactive disqualification applies only from March 26 to April 12, 2024, so his fourth place in the Paris Olympic 200 meters stands.
• The ruling removes the 21-year-old from the upcoming World Athletics Championships in Tokyo after he had previously been cleared by a U.S. tribunal.
