USADA has lifted the UFC strawweight Amanda Ribas’s two-year sanction, the UFC’s anti-doping partner announced Friday. The 25-years-old Brazilian mixed martial artist tested positive for the banned substance ostarine before even making her promotional debut in 2017.
Ribas was suspended for two years in January 2018, retroactive to when the drug test was administered and if the termination didn’t happen she would have been eligible to return next month.
Ribas was unable to identify the source of her failed test, according to a press release, but USADA determined the trace amounts of ostarine found in Ribas’ system was consistent with supplement contamination. Therefore, the agency “believes it is fair to allow Ribas to return to competition after serving the majority of her two-year sanction.”
