On August 22, it was announced that Jones was flagged for a potential doping violation by USADA stemming from his urine test sample that was collected after weigh-ins July 28. He allegedly tested positive for Turinabol , an anabolic steroid . Jones was placed on a provisional suspension as a result of the positive drug test and he is expected to be afforded a full adjudication process.  The "B" sample his failed drug test also confirmed the presence of a banned substance, as announced on September 12. According to the California State Athletic Commission (CSAC), Jones passed multiple out-of-competition tests leading up to the event, as well as a blood test on July 29. That blood test does not significantly aid Jones' case, however, as blood tests do not test for Turinabol.  On the following day, the CSAC officially changed the result to a no contest.
