Former welterweight titlist Luis Collazo, who is aiming to get back into a major fight, signed Wednesday with Golden Boy Promotions.
"I'm honored to be a part of the best team in boxing and now I finally have a chance to show the world what I can do in the ring," Collazo said. "I'm hungrier and better than ever and I'm not gonna stop until I'm back on top of the welterweight division."
Collazo (31-4, 16 KOs), a 30-year-old southpaw from Brooklyn, N.Y., has been quite inactive, in part because he was waiting for his previous promotional agreement with Don King to expire.
Since losing a spirited and close decision challenging then-welterweight titlist Andre Berto in January 2009, Collazo has fought only twice. He returned from a 22-month layoff to stop Franklin Gonzalez in the third round in April.
"Luis Collazo has been a well-kept secret for too long," Golden Boy promoter Richard Schaefer said. "He's a talented former world champion who has fought some of boxing's best and is eager to regain his crown. We will make sure he gets every opportunity to shine in the coming years."
Collazo won a 147-pound title when he secured a split-decision victory against Jose Antonio Rivera in Rivera's hometown of Worcester, Mass., in 2005.
After stopping Miguel Angel Gonzalez in the eighth round in his first defense, Collazo lost the belt to Ricky Hatton on a controversial decision in Boston in May 2006.
Two fights later, Collazo badly injured his hand early in the fight and lost a lopsided decision to Shane Mosley in 2007.
Collazo, who could fight at welterweight or junior middleweight, appears to fit in with Golden Boy, which will begin promoting regular shows under an exclusive agreement with Barclays Center in Brooklyn after it opens.
The arena, which will be the new home of the NBA's New Jersey Nets, is under construction and due to open in September 2012.
Collazo's first bout with Golden Boy has not yet been scheduled.
