Jones’ B sample returned with the same result, flagging the steroid Turinabol in Jones’ test.
Jon Jones has failed his B sample drug test with another positive test for Turinabol. The failure stemmed from a sample taken surrounding his UFC 214 bout against Daniel Cormier, for the promotion’s light heavyweight title. Jones won the bout by KO in the third round. ESPN first reported the news of the secondary sample coming back positive. USADA has since confirmed that Jones’ B sample did not differentiate from his A sample.
