Olympic sprinter Knighton allowed to run at US trials after contamination case
EUGENE, Ore. (AP) — Sprinter Erriyon Knighton tested positive for a banned substance that an arbitration panel determined came from contaminated meat, a decision that keeps the 200-meter specialist eligible to run at the upcoming U.S. Olympic trials.
The 20-year-old from Florida, who holds the under-18 and under-20 records in the 200 meters, tested positive for the performance enhancer trenbolone during an out-of-competition test in March, according to the U.S. Anti-Doping Agency, which revealed details of the case Wednesday.
Though the arbitration panel cleared Knighton to run in the 200, starting June 27, the decision can be appealed by either the Athletics Integrity Unit, which oversees doping in track and field, or the World Anti-Doping Agency.
Neither WADA nor AIU immediately returned emails from The Associated Press seeking comment.
