Knighton, 20, tested positive for performance enhancer trenbolone, a banned steroid, during an out-of-competition test on March 26. But the USADA decided before the start of the domestic qualifiers for the Paris Olympics that no ineligibility would be imposed on Knighton, claiming that the athlete’s positive result for trenbolone was caused by his ingestion of contaminated meat, and allowed him to eventually represent the US at the Paris Olympics, CHINADA said in a statement published on Tuesday. 20 歲的奈頓在3 月26 日的一次賽外測試中，成績增強劑群勃龍（一種違禁類固醇）檢測呈陽性。會取消奈頓的參賽資格中國反興奮劑機構在周二發表的一份聲明中表示，該運動員群勃龍測試結果呈陽性是由於攝入了受污染的肉類造成的，這使他最終能夠代表美國參加巴黎奧運.
