WBC middleweight champion Sergio Martinez (50-2-2, 28KOs) is not stepping away from his demand for Julio Cesar Chavez Jr. (46-1-1, 32KOs) to undergo a random drug testing protocol. On September 15th at the MGM Grand in Las Vegas, Martinez won a twelve round unanimous decision to capture the title. Chavez failed the post-fight drug test, as he came up positive for marijuana. Chavez is demanding a rematch in May of 2013.

Martinez sent Chavez a message.

"[Agree to] anti-doping tests for blood and urine, and we can fight back tomorrow if it was up to me. Boxing needs to be clearn and you have damaged it," Martinez said.
