Pot-smoking Chavez hit in pocket
Julio Cesar Chavez Jr has been fined $20 000 after testing positive for marijuana. The WBC has also ordered the Mexican to undergo treatment.
And on the same day a British heavyweight, Ali Adams, was suspended for two years after testing positive for steroids.
Chavez lost his WBC middleweight title when Argentina's Sergio Martinez beat him on points in Las Vegas last month. Traces of marijuana were found in his urine after the bout.
He has since expressed regret for what he did and issued an apology to fans.
“The WBC fined Chavez Jr $20 000 (nearly R170 000). This sum will be donated to a medical centre that cares for children with cancer," the organisation said in a statement on Thursday.
"The WBC has also decided to suspend him for an undefined time, so he can enter a rehab centre.
“The WBC will open its doors once again to Julio Cesar Chavez Jr, so he can continue his successful career when he feels he can return. The suspension will last as long as the rehab centre advises".
Chavez tested positive for a diuretic in 2009 and was hit with a seven-month ban as well as being stripped of a victory and fined $10nbsp 000 – ten per cent of that fight's purse.
Pre-fight test results have not yet been received by Nevada officials, whom promoter Bob Arum plans to seek leniency from because marijuana is regarded as a recreational drug and not a performance-enhancing substance.
"The Nevada Boxing Commission is independent of this matter … it did not have the courtesy to work with the WBC in this fight," the WBC said in its statement.
Chavez was arrested on a drunk-driving charge last January, only two weeks before a successful title defence. He reached a plea deal in that case that included three years of probation.
British anti-doping authorities said on Thursday Adams, an Iraqi-born professional, tested positive for stanozolol after his four-round loss to former Olympic champion Audley Harrison on May 26.
The ban will run until June 13, 2014, reports Sapa-AP.
UK Anti-Doping legal director Graham Arthur says the positive finding resulted from "a targeted, intelligence-led test."
Adams said the stanozolol may have come from medication he was using for a neck injury. But Arthur says stanozolol "is banned at all times in sport. There is no reason for it to be found in an athlete's system."
Adams has a record of 13 wins, four defeats and a draw.
