The Nevada State Athletics Commission (NSAC) has confirmed that Jon Jones tested positive for two banned substances prior to his scheduled fight with Daniel Cormier at UFC 200 and has extended his temporary suspension.

According to MMAjunkie, NSAC Atty. Caroline Bateman said during a hearing in Las Vegas that Jones’ drug tests came out positive for hydroxy-clomiphene, “an anti-estrogenic agent” and “letrozole metabolite,” an “aromatase inhibitor.” The substances mentioned are consistent with the claim of ex-training partner Rashad Evans that Jones tested positive for estrogen blockers.

Following the results of the test, the NSAC has extended the temporary suspension of Jones’ Nevada fight licence. A formal hearing is set for September or October and Jones will be defended by noted anti-doping attorney Howard Jacobs.

Foxsports reports that both drugs Jones tested positive in are listed on the World Anti-Doping Agency’s (WADA) banned substances list. The drugs are listed as hormone and metabolic modulators, which are not allowed any time in or out of competition.

Estrogen blockers are usually used to counter the effect of another illegal substance such as steroids. Steroids introduce extra testosterone in the body, resulting in the production of additional estrogen. Additional estrogen could result in fat retention or could lead to breast growth in men.

The US Anti-Doping Agency (USADA) tested Jones on June 16 ahead of his title unification fight with Cormier at the T-Mobile Arena in Las Vegas on July 9. Jones was removed from the card three days before the fight when his “A” sample came back positive for a banned substance.

Former middleweight champion Anderson Silva replaced Jones at UFC 200. Cormier defeated Silva via unanimous decision.

UFC President Dana White was angry at Jones and said he isn’t talking to him any longer.

“Listen, I’m not the biggest Jon Jones fan right now, but I truly believe that he did take a supplement that had (banned) stuff in it, and it wasn’t intentional,” he said.

But he did say that Jones should have known better already considering the “history of just absolute madness” that the interim champ has been through.
