During Monday’s Nevada Athletic Commission hearing, it was announced UFC interim light heavyweight champion Jon Jones (pictured) tested positive for two estrogen blockers in the June 16 out-of-competition drug test administered by the USADA that forced his removal from UFC 200.
According to NSAC attorney Caroline Bateman, Jones had hydroxy-clomiphene, “an anti-estrogenic agent” and letrozole metabolite, an “aromatase inhibitor” was discovered in both Jones’ A and B samples. Both substances are banned by the World Anti-Doping Agency during in- and out-of-competition periods.
The NAC placed Jones on temporary suspension until he can stand before them at a formal hearing later this year.
