Josh McCown will start at quarterback for the Oakland Raiders on Sunday in Jacksonville with rookie JaMarcus Russell slated to come off the bench as a reserve. Coach Lane Kiffin had considered giving Russell his first career start against the Jaguars and then bring in McCown to finish the game. Russell, this year's No. 1 overall draft pick, has played five series in two games as a reserve so far. Kiffin said Russell could come in during the first half and possibly might finish the game depending on how the situation played out.
