The U.S. Anti-Doping Agency today urged caution while confirming a report that Jon Jones passed a post-fight blood test in connection with his title win at UFC 214.

“It’s only fair to let due process occur before jumping to any conclusions,” USADA spokesperson Danielle Eurich said in a statement sent to MMAjunkie.

Jones (23-1 MMA, 17-1 UFC), Eurich said, came up negative for banned substances in a blood test administered after his July 29 fight against Daniel Cormier (19-2 MMA, 8-2 UFC), despite failing a urine test for the steroid turinabol collected the day of the event’s weigh-ins. The passed test added to two out-of-competition samples – collected July 6 and 7 – that also came up negative, adding more mystery to the test Jones failed.

Earlier today, MMAFighting.com cited multiple sources close to Jones in reporting Jones’ post-fight negative. Eurich, however, cited Jones’ agent – presumably longtime rep Malki Kawa – as the source.

“Given that Mr. Jones’ agent has publicly commented on this case, we can confirm Mr. Jones provided a urine and blood sample on July 6th and an additional urine sample on the 7th – all of which were reported negative,” Eurich said. “On July 28th, his urine sample tested positive for turinabol – as confirmed previously – then after the fight he provided a blood sample that was reported negative.”

The failed test triggered Jones’ second anti-doping case with USADA after an out-of-competition test found two banned estrogen blockers in his system prior to a title unifier against Cormier at UFC 200. He appealed the findings and was still found to be culpable despite not intentionally cheating. A one-year suspension followed.

Jones’ team currently awaits the results of the “B” sample from the positive test on July 28. If confirmed, the sides are likely to head to arbitration, where Jones, who knocked out Cormier via head kick, would face up to a four-year suspension if the findings are upheld.

Eurich stated the absence of turinabol in Jones’ blood is explained by the parameters of the test and indicated the public should hold off before making any conclusions.

“The prohibited anabolic steroid turinabol is only tested for in urine screens and not in blood tests,” she said. “Urine and blood screens are complimentary to each other and don’t analyze for the same substances. Importantly, Mr. Jones is innocent unless and until the established process determines otherwise. It’s only fair to let due process occur before jumping to any conclusions.”

Jones’ rep and several other fighters ensnared in anti-doping violations have accused USADA of urging the public to do the opposite by announcing potential cases before adjudicating them. Jones, via Kawa, has steadfastly maintained innocence in both anti-doping cases and is “crushed” by the latest positive.

UFC President Dana White has said if Jones is again suspended, Cormier will be crowned the UFC light heavyweight champion.
