UFC welterweight Li Jingliang will not face sanctions despite testing positive for for a prohibited substance, U.S. Anti-Doping Agency officials today announced.

In a sample collected prior to his July win over Anton Zafir at The Ultimate Fighter 23 Finale, Jingliang tested positive for “for trace amounts of clenbuterol,” according to USADA officials, who independently administer the UFC’s anti-doping program. However, a subsequent investigation revealed the substance, which is prohibited at all times, was “ingested by him without fault or negligence.”

The Chinese fighter provided the out-of-competition urine sample in question on May 18. However, USADA officials determined Jingliang’s positive result was likely due to ingesting animal proteins that were tainted with the anabolic agent.

“During its investigation into the circumstances that led to the positive test, USADA interviewed Jingliang and reviewed all available relevant evidence, including Jingliang’s whereabouts, dietary habits, and the laboratory reports demonstrating very low parts per billion concentrations of the prohibited substance in the athlete’s urine sample,” USADA’s statement reads. “USADA concluded that the presence of clenbuterol in the athlete’s sample very likely resulted from clenbuterol contaminated meat consumed in China. As a result, Jingliang will not face a period of ineligibility for his positive test. Furthermore, Jingliang’s competitive results from his bout on The Ultimate Fighter Finale card have not been disqualified because a sample collected in connection with that bout on July 8, 2016, by the Nevada State Athletic Commission was reported as negative.”

The finding is in line with other recent flagged tests from “problem” countries identified by the World Anti-Doping Agency, as both China’s Ning Guangyou and Mexico’s Augusto Montano were also given similar reprieves.

While it seems unlikely, NSAC officials could issue a suspension of their own should they deem such a move necessary.

Jingliang (11-4 MMA, 3-2 UFC) picked up his third UFC win in July when he knocked out Anton Zafir (7-3 MMA, 0-2 UFC) at The Ultimate Fighter 23 Finale. That continued his run of alternating wins and losses, but got him back in the win column after a submission loss to Keita Nakamura in September 2015.
