Another UFC fighter has failed a drug test from the U.S Anti-Doping Agency (USADA).
Light heavyweight fighter Nick Roehrick has tested positive for a banned substance.
The UFC announced Roehrick had potentially failed a drug test on Thursday.
Roehrick has one fight in the UFC. He made his UFC debut last month at The Ultimate Fighter Redemption Finale. On that night, he lost to Jared Cannonier by TKO in the third round of their fight.
Roehrick failed an out-of-competition drug test from a sample that was collected on Aug. 8. This means Roehrick was clean of any performance-enhancing drugs when he made his UFC debut on July 7.
Prior to joining the UFC, Roehrick was undefeated with seven wins. His record includes two wins by submission and one win by knockout.
