The longtime UFC light heavyweight champion tested positive for a banned substance in an in-competition USADA test in relation to his fight with Daniel Cormier on July 29 in Anaheim, Calif., and has been provisionally suspended, sources told MMA Fighting. In that bout, Jones defeated Cormier by third-round TKO to regain the UFC light heavyweight belt.

Jones has been stripped of the title and Cormier will get it back, per TMZ, which was the first outlet to report the news. UFC president Dana White told ESPN that has not been decided yet. The UFC confirmed the Jones positive test in a statement posted to its website.

TMZ reported that Jones tested positive for the steroid turinabol, which carries a two-year suspension from USADA for first-time offenders and longer for multiple-time offenders.

Jones, 30, also tested positive prior to what would have been a bout with Cormier at UFC 200 in July 2016. Jones was pulled from the fight and provisionally suspended three days prior to that event. He was suspended and served a one-year ban by USADA for testing positive for two banned substances, clomiphene and letrozol.

This is the latest in a string of issues Jones has had in recent years, including a felony hit-and-run arrest and DUI. The comeback victory over Cormier last month was supposed to be part of a greater redemption story for Jones.

The California State Athletic Commission (CSAC), which also has jurisdiction over the matter, confirmed the positive test Tuesday with MMA Fighting.

“The California State Athletic Commission has been made aware of Jon Jones’ test results and is looking into the matter,” CSAC executive officer Andy Foster said. “The Commission takes these matters very seriously and will take any appropriate actions necessary after a thorough review of the situation. As with all fighters, Mr. Jones is entitled to due process and the Commission will work with the United States Anti-Doping Agency (USADA) to get all of the proper information.”

The UFC released the following statement below Tuesday evening.

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.
