Margarito lost his WBA welterweight title to Mosley
Former WBA welterweight champion Antonio Margarito has had his licence revoked for one year by the California State Athletic Commission.
Margarito and trainer Javier Capetillo have been banned for putting a plaster-like substance under Margarito's hand wraps for his fight with Shane Mosley.
The pads, confiscated last week, are still being tested by the commission.
Mexican Margarito lost his WBA welterweight title to Mosley in January via a ninth-round stoppage.
Margarito, who had claimed the title from Puerto Rico's Miguel Cotto last July, did not fight with the hard pads in his gloves, but the commission still voted 7-0 to revoke both Margarito and Capetillo's licences.
