TMZ was the first to report the news and their report stated that the steroid Turinabol was found in Jones’ system. The UFC issued the following statement shortly after the news broke:
The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Jon Jones of a potential Anti-Doping Policy violation stemming from an in-competition sample collected following his weigh-in on July 28, 2017.
USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case involving Jones, as it relates to the UFC Anti-Doping Policy and future UFC participation. Under the UFC Anti-Doping Policy, there is a full and fair legal process that is afforded to all athletes before any sanctions are imposed. The California State Athletic Commission (CSAC) also retains jurisdiction over this matter as the sample collection was performed the day before Jones’ bout at UFC 214 in Anaheim, CA, and USADA will work to ensure that the CSAC has the necessary information to determine its proper judgment of Jones’ potential anti-doping violation.
Additional information will be provided at the appropriate time as the process moves forward.
Both UFC president Dana White and their VP of Athlete Health and Performance Jeff Novitzky spoke to members of the media on Tuesday night in Las Vegas. They confirmed the news of the drug test but would not comment on the specific substance that Jones is believed to have had in his system. Novitzky added that the in-competition drug test took place after the weigh-ins for UFC 214 on Friday July 28th.
White has stated that Jones has not been stripped of his championship yet, but if Jones is found guilty, the win would be overturned and it’s a formality that he would have to be stripped of the title. When asked what White would do with the championship, he indicated it would likely return to Cormier.
White added that they were in talks with Jones to move up to heavyweight in his next fight and said they were discussing a fight between Jones and heavyweight champion Stipe Miocic for December in Detroit.
Jones’ management team provided the following statement to MMA Fighting:
We are all at a complete loss for words right now. Jon, his trainers, his nutritionists and his entire camp have worked tirelessly and meticulously the past 12 months to avoid this exact situation. We are having the samples tested again to determine the validity or source of contamination. Jon is crushed by this news and we are doing whatever we can as a team, to support him.
This would be the second USADA violation that Jones has faced, with the first one prior to UFC 200 and forced Jones to be removed from the main event of that card in July 2016. Jones ended up being handed a one-year suspension for that out-of-competition failure.
Jones just turned 30-years old last month and returned at UFC 214 following a 15-month hiatus to regain the UFC light heavyweight title, stopping Daniel Cormier in the third round of their main event bout.
