Cynthia Calvillo may be facing sanctions to go along with her first professional loss in MMA.
Calvillo has been informed of a potential UFC anti-doping policy violation, the UFC announced in a statement Wednesday evening. She tested positive for Carboxy-Tetrahydrocannabinol (Carboxy-THC) — over the limit of 180 ng/mL — in an in-competition drug test administered by the U.S. Anti-Doping Agency (USADA). The test was in relation to her unanimous-decision loss to former champion Carla Esparza at UFC 219, which took place Dec. 30 in Las Vegas.
Carboxy-THC is a “metabolite of marijuana and/or hashish,” per the statement.
