Report: Gastelum pulled from UFC 212 after potential failed marijuana test

Kelvin Gastelum has been placed on provisional suspension and removed from his June 3 bout against Anderson Silva at UFC 212. The suspension comes after a test revealed tetrahydrocannabinol (THC) - a psychoactive component in marijuana - in his system, according to MMAJunkie.com.

The U.S. Anti-Doping Agency informed Gastelum of the potential violation Thursday, providing a full statement:

The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) informed Kelvin Gastelum 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 his recent bout in Fortaleza, Brazil on March 11, 2017.

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

As a result of the potential anti-doping violation against Gastelum, USADA has placed him under a provisional suspension. While the UFC Anti-Doping Policy affords Gastelum full and fair due process rights before any possible adjudication of his case, because of the proximity to Gastelum's scheduled June 3rd bout against Anderson Silva, Gastelum is being removed from the card and a replacement is currently being sought.

Gastelum was slated to enter the contest on a three-fight winning streak.

UFC 212 will take place in Rio de Janeiro.
