Tough Mexican southpaw Marvin Quintero (25-3, 21 KOs) has been contacted by the team of undefeated Timothy Bradley. They requested him to take part in Bradley's camp as a sparring partner. Quintero has accepted and plans to spend the entire month of May in Bradley's camp, which is taking place in California.

Quintero is waiting for a finalized date for his mandatory title shot against IBF lightweight king Miguel Vazquez, while Bradley is preparing for his June 9th collision with WBO welterweight champion Manny Pacquiao. Vazquez has until October to make his mandatory defense.

"We will take this great opportunity to learn from Bradley, who is also a great person. I'll help as much as I can and I will also learn a lot. I think he has a good chance to beat Pacquiao and go down in history," Quintero said.
