Cynthia Calvillo smoked by USADA following UFC 219 loss to Carla Esparza

As if losing wasn't bad enough, Ultimate Fighting Championship (UFC) strawweight up-and-comer Cynthia Calvillo, 30, has now been informed by United States Anti-Doping Agency (USADA) that she came back positive for marijuana metabolites in the wake of her UFC 219 loss to Carla Esparza last month in Las Vegas, Nevada.

The official statement, courtesy of UFC.com:

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 has the right to appeal and request an arbitration hearing.

The loss was the first of her mixed martial arts (MMA) career and dropped the Californian to 6-1 overall. Since this is her first offense, a disciplinary suspension would still leave her eligible to compete later this year.

Stay tuned.
