Jon Jones fails B sample, UFC 214 failed drug test confirmed

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.

“Mr. Jones’ B sample has confirmed the A sample findings,” USADA told MMAFighting through a spokesperson. “Importantly — as previously stated — due process should occur before drawing any conclusions about this matter.
