EUGENE, Ore. (AP) — Sprinter Erriyon Knighton tested positive for a banned substance that an arbitration panel determined came from contaminated meat. The decision 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. Its CEO says the contaminated meat came from oxtail at a bakery in central Florida.
