Middleweight contender Brian Vera (23-6, 14KOs) has some doubts about Julio Cesar Chavez Jr. (46-1-1, 32KOs) being capable of making the super middleweight limit of 168-pounds. The two fighters are scheduled to face each other on September 28th at the StubHub Center in Carson, California.

Chavez's struggles to make the middleweight limit are well documented but he always manages to make the weight. The Mexican star has been inactive since last September's decision loss to Sergio Martinez, and numerous photos have surfaced over the last few weeks that showed Chavez weighing far beyond 168-pounds.

Chavez-Vera was pushed back several times, and the weight limit was increased several times.

"I don't think he'll make [168], but he's going to get penalized for it and [my team and my promoter] are going to make him lose the weight. [The weight for our fight] changed so many times already. I saw him [two weeks] ago and he looked big," Vera told BoxingScene.com.

Chavez is well known for making weight and then packing on 20-pounds or more by the time of the fight. Vera has been working with trainer Ronnie Shields to combat Chavez's mauling style when he presses his opponents against the ropes and wears them down by pushing his full weight on them.

"I have to use speed...just really stepping around him and not so much movement. He's like a robot and you have get around him. Ronnie has me doing a lot of things in the gym for that," Vera said.

"Sergio Martinez is a little guy. I once went to go spar with him for three weeks. I think I'll be the strongest [opponent] that he's fought as far as physical. As far as being physical, I think I'll be alright, but we'll have to see. "
