Former WBC middleweight champion Julio César Chávez Jr. is refusing to sign a contract extension with longtime promoter Top Rank, because the Mexican star indicates that he's not being properly compensated for his fights. He says the extension provided is lacking the money that he feels is adequate for a fighter of his caliber.

Top Rank is trying to finalize a fight on July 19th with Gennady Golovkin, but the fight can't happen unless Chavez signs the extension.

"They want to make me sign an extension of my [promotional] contract, but they are not giving me the money that I'm actually worth to fight. They have never showed me numbers that I generate and they also want to force me into an [extension of] three fights for less money than I'm being offered elsewhere," Chavez said.

"All I ask is that there is no extension and I'm paid what I should be, [given] the percentage that I deserve. I am open to work with Top Rank, as long as they want to work with me one hundred percent, fight-by-fight."

"My father was not very well taken care of [during his career]. He is very proud of me because I'm making these decisions, and he has supported me. We talked about it, because he doesn't want me to take the same abuses."
