LAS VEGAS (AP) – A doping test on Jon Jones’ backup sample has confirmed the positive results that forced the UFC to drop the pound-for-pound star from his main-event bout at UFC 200 this week.
USADA spokesman Ryan Madden confirmed an independent lab’s findings on Jones’ B sample Friday.
Jones was removed from the UFC’s landmark card on Wednesday night after the potential doping violation was first discovered in a sample taken June 16.
Jones and his management haven’t revealed the substance for which Jones tested positive, but the fighter tearfully denied knowingly using any performance-enhancing drugs.
Jones could face a multiyear suspension from the Nevada Athletic Commission.
