Julio Caesar Chavez Jr (45-0-1 31KOs) has had a rivalry with undisputed middleweight king Sergio Martinez (49-2-2 28KOs) ever since he won the WBC middleweight title last year in the summer.
The reason for this is because Sergio Martinez was the WBC belt holder until the WBC stripped him for being unable to defend it against Zbik. Chavez would go on to win the belt and Martinez has been chasing Junior since then to win back his belt.
Almost a year gone by, Martinez is that much closer to reaching his goal of fighting Junior.
After Junior's last win against Marco Antonio Rubio, the WBC mandated that he defend his title against Sergio Martinez next. Arum was able to squeeze in a fight with Andy Lee before being forced to fight or vacate.
Earlier this month, Sergio sat down and signed a contract to fight the winner of Chavez Jr. vs. Lee on September. All that was needed was a signature from Dibella, Arum, Lee and Chavez Jr.
Signatures from Lee and Dibella wasn't a problem as Lee is promoted by Dibella and Dibella is Martinez's promoter. The problem was getting Chavez Jr. and Arum to sign. It seemed Arum was uninterested in making the fight as he continuously set up voluntary defenses against other people and alluded to Martinez not being a big draw in the sport.
According to the WBC website, President Jose Sulaiman confirmed that Chavez Jr. signed his part of the contract for the winner of his match against Lee to fight against Sergio Martinez later this year.
There's still a good possibility that these two won't meet in the ring. Junior could lose against Lee or could cite injury before his fight with Martinez.
Until both men meet in the ring and the bell sounds, I won't be completely convinced that this fight is going down.
