Cynthia Calvillo tested positive for marijuana metabolites in an in-competition drug screening at UFC 219.

The promotion announced the failed USADA test in a statement on Wednesday:

The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) informed Cynthia Calvillo of a potential Anti-Doping Policy violation involving Carboxy-Tetrahydrocannabinol (“Carboxy-THC”) which is a metabolite of marijuana and/or hashish, above the decision limit of 180 ng/mL, stemming from an in-competition sample collected in conjunction with her recent bout in Las Vegas, Nevada on December 30, 2017, UFC 219: Cyborg vs. Holm.

USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case involving Calvillo, as it relates to the UFC Anti-Doping Policy and future UFC participation. Because the Nevada Athletic Commission was the regulatory body overseeing the fight in Las Vegas and has licensing jurisdiction over Calvillo, USADA will work to ensure that the Nevada Athletic Commission has the necessary information to determine its proper judgment of Calvillo’s potential anti-doping violation. Additional information will be provided at the appropriate time as the process moves forward.

Calvillo lost a unanimous decision to Carla Esparza in a featured 115-pound clash at UFC 219, her first defeat in six professional appearances. The 30-year-old Team Alpha Male product began her Octagon tenure with victories over Amanda Bobby Cooper, Pearl Gonzalez and Joanne Calderwood.
