Former WBC middleweight champion Julio Cesar Chavez Jr. (46-1-1, 32KOs) is open to the idea of having a rematch with Marco Antonio Rubio (56-6-1, 49KOs). Chavez won a twelve round decision over Rubio last February in Texas, but there was controversy after the match.

Rubio claims that neither he or Chavez were drug tested by the local commission and there have been mixed reports on whether or not the tests took place. Last September Chavez tested positive for marijuana after losing a decision to Sergio Martinez.

Chavez is being positioned to return in the spring, with Matthew Macklin being mentioned as the potential opponent. Chavez has no problem with facing Macklin but he also named Rubio as well. If Chavez wins his next fight, there could be a fall rematch with Martinez.

"I would like to fight Macklin or Rubio before the rematch [with Martinez] or [a fight] with the WBC's number one challenger for another title shot," Chavez stated.

Rubio responded on the social networks with - "Whenever you want, and anywhere but Texas and anti-doping tests before and after the fight. I'm ready."

Chavez would reply back - "Rubio, I can give you the opportunity. This is boxing but do not say that brother, I beat you clean."
