Jon Jones popped for estrogen blockers, suspended indefinitely

The banned substances which turned Jon Jones’ life into a spiral has been formally revealed.Former UFC light heavyweight champion Jon Jones tested positive for Hydroxy-clomiphene, an anti-estrogenic agent, and Letrozole metabolite, an aromatase inhibitor, during a June 16 out-of-competition drug test administered by USADA, according to multiple reports.

The Nevada Athletic Commission revealed the findings at Monday’s meeting in Las Vegas. Both Rashad Evans (for CBS Sports) and Chael Sonnen (on Joe Rogan’s podcast) previously reported Jones popped for estrogen blockers.

The commission unanimously issued Jones a temporary suspension pending a full hearing, which will be held at a date to be determined, likely in September or October.

Jones and the UFC were informed of the test failure on July 6, three days before Jones was scheduled to headline UFC 200 against Daniel Cormier. Jones was pulled from the bout and Cormier eventually met Anderson Silva in a non-title fight, which Cormier won via unanimous decision.

Jones will soon meet again with the NSAC to determine the proper ruling on, as well as what Jones’ defense will be in light of this positive test.
