Raiders quarterback Josh McCown will miss Sunday's game against the Dolphins with a broken toe on his left foot, giving Daunte Culpepper the start against his former team. McCown has not practiced all week but coach Lane Kiffin waited until Friday to officially declare that he would not be able to play Sunday. McCown broke his toe in the first quarter of last week's 26-24 victory over Cleveland. Culpepper replaced him in the second half and finished the victory. Culpepper, who was released by the Dolphins in July after one season, will get his first start since last Oct. 1 for Miami.
