Antonio Margarito on Pacquiao Fight: "I Won't Quit Like Oscar De La Hoya Did."

Taking a swipe at Oscar de la Hoya, his former sparring partner, Mexican-American boxer Antonio Margarito said he won't quit like de la Hoya did during his last fight with Manny Pacquiao.

De la Hoya fought Manny Pacquiao in December of 2008 and lost when de la Hoya's corner threw in the towel after eight rounds.

“I will knock Pacquiao out,” the Tijuana Tornado told Boxing Scene.com. “This is the fight of my life and Manny will be in for a tough night, I won’t quit like de la Hoya did."

But Pacquiao's trainer Freddie Roach said Margarito won't last and will throw in the towel like Erik Morales also did when he quit in the 10th round of his second fight and in the third round of his third fight with Pacquiao.

Margarito was Oscar de la Hoya's sparring partner until 2008 and they parted ways after de la Hoya refused to fight him. Since then, they have not been on speaking terms.

"I don't know what he has against me, I really don't understand. What I do know is that he had a big influence in the California State Athletic Commission with everything he said against me,” said Margarito.

De la Hoya has openly campaigned for the permanent revocation of Margarito's boxing license in California and Nevada after the Mexican boxer was caught with illegal hand wraps minutes before stepping into the ring to face Shane Mosley at the Staples Center in Los Angeles.

Meanwhile, Margarito has just completed his two-week initial training where he concentrated on mountain road work and has moved to Oxnard, Calif., for the remainder of his training before heading for Texas for the final phase leading up to the fight on Nov. 13.

Margarito's trainer Robert Garcia, who is a former IBF junior lightweight champion, said Margarito is confident he can top the Filipino boxer.

“We got a lot done in the first two weeks and Tony looks great. I love his focus and intensity and our first phase of training camp was an eye- opener for him and me. The first two weeks have been really terrific and productive,” said Garcia.

Margarito, who is a three-time world champion, said he knows how important the fight is to him and the people of Mexico and will prove to everyone that he is one of the best fighters in the world.

“The belt is very important to me, but the most important thing is to give the fans a great fight and one that they will remember for a long time. I love to fight and Manny has proven that he is a warrior. This fight is going to be a war,” Margarito continued.

On the side of Pacquiao, who is training with coach Freddie Roach in the mountain city of Baguio in the Philippines, will begin his first sparring session with Michael Medina and Glen Tapia on Thursday.

The popular Filipino boxer has taken a break from his training and played basketball for about two hours with the local team. He also did some running at Burnham Park and chatted with fans and onlookers while doing his usual rounds.

His favorite dog "Pacman" was with him while jogging along the road.
