Ronnie Shields, the trainer for Brian Vera, is not happy with the latest turn of events for this Saturday's fight against Julio Cesar Chavez Jr. at the StubHub Center in Carson, California.

A nerve was struck after Shields read a story on BoxingScene.com, where Chavez's promoter, Top Rank CEO Bob Arum, said the weight for Chavez-Vera has not been determined.

Apparently Arum wants to have both fighters weigh-in on Wednesday - and based on those numbers a decision will be made as to Saturday's fighting weight.

Serious rumblings began on Monday, related to Chavez having difficulties making the super middleweight limit. The fighting weight for Chavez-Vera has already been increased several times, according to an interview with Vera two weeks ago.

"We’re going to take a look at what the fighters weigh tomorrow and decide what the weight limit will be on the fight,” Arum said. “Right now there’s no determination on that.”

Shields will not allow his fighter to take part in a Wednesday weigh-in, making it very clear that his boxer signed a contract to fight at 168-pounds and doesn't see any reason to step on a scale until Friday.

Vera is already at the contract limit, says Shields.

"Arum said he's going to put them on a scale tomorrow to determine what the weight is. I'm not letting my guy get on a scale - f*** that. My guy is not getting on a damn scale. My guy signed a contract for 168-pounds, to weigh in on Friday at whatever time they choose to weigh in on Friday - and that's what we're going to do," Shields told BoxingScene.com.

"We are not going to weigh in on Wednesday. We have a contract for 168-pounds and that's what we are fighting at - 168. Otherwise, they better bring a big ass check to the weigh-in."

"We have a lot of respect for Bob Arum. He's been a promoter in this business for years and years. He should know already - how is he going to pre-determine what the weight is going to be? We signed for 168-pounds and that's what Brian Vera is going to weigh in at - and he's not going to weigh in until Friday."
