NAPA -- Korey Bosworth, a first-year linebacker out of UCLA and the nephew of former Oklahoma All-America linebacker Brian Bosworth, signed with the Raiders Thursday and will accompany the team to Arizona for their game against the Cardinals.

Bosworth, 6-foot-1, 230 pounds, originally signed with Denver as an undrafted free agent in 2010, spent parts of the 2010 and 2011 training camps with the Detroit Lions, and played in the Lions' preseason opener last week against Cleveland.

Bosworth's twin brother, Kyle, plays for the Jacksonville Jaguars.
