Oakland Raiders head coach Tom Cable said that Jason Campbell will start at quarterback on Sunday against the Kansas City Chiefs. Campbell is making his fourth consecutive start in place of the Bruce Gradkowksi. Cable said Gradkowski’s separated right shoulder (throwing arm) is healing, however he still can’t make all the throws and the shoulder wouldn’t hold up through an entire game. Campbell has led Oakland to back-to-back wins in the last two weeks during which the team had 500-plus yards in total offense for the first time in franchise history.
