Julio Cesar Chavez Jr. didn’t disclose that he had used or was using any substances, prescription or otherwise, prior to his Sept. 15 fight with middleweight champion Sergio Martinez, according to Keith Kizer, executive director of the Nevada State Athletic Commission, who spoke to BoxingScene.com via email on Friday morning.
Chavez tested positive for marijuana metabolites. The 26-year-old has blamed a prescription medication he took prior to the decision loss, according to a report that ran earlier today on BoxingScene.com.
"I'm not a drug addict, I have never smoked marijuana,” Chavez was quoted as saying on Mexican television. “For years I have had insomnia, so I went to the doctor and he prescribed some drops for me that contained cannabis. I stopped taking them before the fight with 'Maravilla' Martinez, and I didn't think I was going to test positive."
Kizer said that a hearing on Chavez will probably occur near the end of October.
