Jon Jones had steroids in his system prior to his UFC 214 grudge match against Daniel Cormier. The United States Anti-Doping Agency (USADA) confirmed this after the “B” sample from his most recent failed drug test also came back positive.

Often regarded as the greatest fighter in UFC history, Jones is now facing a suspension that could see him barred from mixed martial arts competiion for up to four years.

Jones is no stranger to controversy. He has been suspended and fined by athletic commissions, stripped of his championships by the UFC three times, and has been taken into custody on multiple occasions for incidents outside of the cage.
