By José Sulaimán:

Numerous media outlets have reported that WBC middleweight world champion Julio Cesar Chavez Jr. will fight Marco Antonio Rubio on February 4, 2012.

The governing WBC Rules and Regulations require a written formal petition for the sanctioning of any official WBC bout before a formal announcement takes place and ticket sales start. As of this date, the WBC has not received any communication from any promoter concerning a Chavez versus Rubio fight.

The WBC therefore does not endorse and disapproves any public announcement or ticket sales suggesting that the WBC has sanctioned the fight, or using the WBC name or trademarks until there is full compliance with the WBC Rules and Regulations.
