With so much controversy, and Chavez's stock never lower, he and Vera will meet in a scheduled 12-round super middleweight rematch on Saturday night.
Chavez (47-1-1, 32 KOs), who turned 28 on Feb. 16, claimed that he took training very seriously.
"This is a real training camp. I'm training, I'm watching my weight, I'm watching my diet. I'm taking care of everything," Chavez said. "I owe the fans a great performance and that is what they will get. I will make the 168-pound limit with no problem and I will be able to do the things I could not do in first fight. I will have better movement, I will be more consistent and I will fight 12 hard rounds if that is what it takes to win this second fight. Vera is a tough guy with a good chin, but I will do my best to send him home early."
He said that there were no corners cut and that he will make 168 pounds without issue at Friday's weigh-in.
"Vera has not seen the best Julio," Chavez said. "I had my best training camp since I fought Andy Lee [in June 2012]. I am ready to fight. Having my little daughter Julia with me gives me extra motivation. Vera earned his second opportunity because of the way he fought in our first fight. Vera is a true warrior. I have had much success in Texas, especially in San Antonio, and am looking forward to giving the fans something they can remember, hopefully the fight of the year."
Chavez even said he might come in a bit under 168 and that a return to the 160-pound middleweight division isn't out of the question for the right bout.
"It wouldn't surprise me if I am a couple of pounds under on Friday and 160 is still on my mind," he said. "There are fights that might be worth my while to get down."
As for making 168, Chavez has another motivation besides his baby. If he doesn't make weight, he will forfeit $250,000 to Vera, according to Arum and Artie Pelullo of Banner Promotions, Vera's promoter.
"He's not going to get any more money out of me than what he's getting paid," Chavez said.
In the highly significant co-feature, two-time Olympic gold medalist Vasyl Lomachenko (1-0, 1 KO), 26, of the Ukraine, the 2013 ESPN.com prospect of the year, aims to set a boxing record by winning a world title in his second professional fight when he challenges featherweight titleholder Orlando Salido (40-12-2, 28 KOs), 33, of Mexico, who will be making the first defense of his third title reign.
Looking back on the first fight, Chavez said he believes he beat Vera (23-7, 14 KOs), 32, of Austin, Texas, but knows that he did not have his best performance.
"I wasn't happy the way I fought that night," he said. "I was not at my best, but I think it was an entertaining fight. Bryan and I went in there and gave the fans their money's worth, regardless of how good we are or how we feel we entertain. I can't do anything about the decision. That's not my job. The judges' decision is out of my hands, but I felt like I won the fight.
"It was a close fight, but I never thought I lost the fight. I had him hurt a few times in the fight. Maybe he threw more punches but I thought my punches were the best punches of the night and doing more damage, so it never crossed my mind that I lost. Maybe he deserved a draw."
Vera, who stuck to trainer Ronnie Shields' game plan to perfection, said he plans to pick up where he left off the first time around.
