Jon Jones failed a US Anti-Doping Agency test ahead of his light-heavyweight title fight with Daniel Cormier at UFC 214, it has been revealed.

In the early hours of Wednesday morning, the UFC released a statement confirming a story broken on TMZ that Jones, 30, had failed a USADA test for the second time in his career.

“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,” the UFC confirmed in a short statement.

“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.”

TMZ broke the story and claimed that Jones will be stripped of his belt following a positive test for Turinabol, an anabolic steroid.

This is the second time that Jones has failed a USADA drugs test, having tested for banned substances in the build-up to UFC 200, when he was scheduled to fight Cormier for a second time.

Jones was pulled from the event and banned for one year. He could now face a ban four-times that in length, which would likely leave his MMA career in tatters.
