As first reported by ESPN, UFC light heavyweight champion Jon Jones’ “B” sample has returned positive for the same substance as his “A” sample. A USADA spokesperson provided the following statement to Bloody Elbow:
"Mr. Jones B sample has confirmed the A sample findings. Importantly - as previously stated - due process should occur before drawing any conclusions about this matter."
There has been some confusion about what, exactly, a positive “B” sample tells us, with some people believing it means Jones has been definitively convicted, or that he no longer has any meaningful defense.
