WBC middleweight champion Julio Cesar Chavez Jr. has blasted his most recent opponent, Marco Antonio Rubio. Earlier this month in San Antonio Texas, Chavez won a twelve round unanimous decision over Rubio. After the fight was over, Rubio became very upset because the local commission never administered any post-fight drug tests.

Earlier this week, Rubio's handlers filed a petition to overturn the loss to Chavez. They question how the boxer weight shifted from 159.5 to 181-pounds in a single night and they also demand answers on why the WBC never held their 30-day and 7-day weight checks.

"Rubio is the most fraudulent and cowardly man that I've ever known. I can not believe that [Rubio and his team] continue to talk won't accept his defeat. We won," Chavez said.
