Devastating news shook the world of MMA when it was revealed that Jon Jones was flagged by USADA for a potential Anti-Doping Policy violation just days ahead of his light heavyweight title fight against champion Daniel Cormier.

Jones and his team arranged a press conference last Thursday to address the situation, but nothing has been released on what Jones tested positive for.

Speaking on the Joe Rogan podcast on Monday, Chael Sonnen claimed that Jones tested positive for two estrogen blockers.

Interestingly, Rashad Evans also said that he was told by Jones’ camp that “Bones” tested positive for estrogen blockers on a CBS Sports report on Thursday.

Jones’ manager Malki Kawa spoke on “The MMA Hour” on Monday and asserted Jones would never knowingly cheat and said they are still keeping the information confidential on what Jones tested positive for until they can address everything involved and where the substance came from.
