Former unified lightweight titleholder Nate Campbell signed a promotional contract with Golden Boy Promotions, according to a press release from the Los Angeles-based company.

Campbell (33-5-1, 25 knockouts), a former junior lightweight and lightweight standout, is currently campaigning at junior welterweight, a division packed with experienced veterans, talented young titleholders and prospects that include former champ Ricky Hatton, Timothy Bradley, Amir Khan, Marcos Maidana, Paul Malignaggi, Devon Alexander, Juan Urango, and Victor Ortiz.

Golden Boy Promotions represents Hatton, Maidana and Ortiz, along with Campbell, who is looking for a shot at one of his fellow 140-pound standouts in 2010.

“I am really excited to become a part of the Golden Boy Promotions team,” said Campbell. “I am confident that Golden Boy will be able to help me to achieve everything that I am still looking to accomplish in my career and I couldn't be happier.”

Campbell, 37, went undefeated in his first 23 professional fights. During his nine-year career, he has battled some of the sport's biggest names including former world champ Joel Casamayor, Bradley and Almazbek Raiymkulov, but he is most remembered for his battle with then-undefeated Juan Diaz in which he captured the WBA, WBO and IBF lightweight belts by handing Diaz his first career defeat in March of 2008.

“Nate Campbell has already shown that he has everything it takes to be a great champion,” said Oscar De La Hoya, President of Golden Boy Promotions. “He has battled some of boxing's greatest fighters and is ready to make a run at another world title in 2010.”
