LAS VEGAS (AP) — Golden Boy Promotions will put boxing matches and mixed martial arts fights side-by-side in a new partnership with Affliction, the fledgling MMA promoter run by an apparel company.

Golden Boy and Affliction will be equal partners in a venture that will put on at least four multisport events starting in 2009, Golden Boy CEO Richard Schaefer said Saturday. Many smaller attempts have been made to pair the two combat sports on the same cards, but Golden Boy and Affliction hope to be the first to do it on a major scale.

"I think the two worlds have finally merged, and this is a perfect example," Affliction vice president Tom Atencio said.
