Josh McCown wasn?t at practice this morning. He injured his right thigh against the Chicago Bears, prompting him to jokingly ask if anyone wanted to ?trade quads? with him on Monday. If Lane Kiffin needed an excuse to play JaMarcus Russell, he?d have one if McCown were out. If Russell is the second quarterback, Kiffin could play Russell for a couple of series a half and make Andrew Walter the inactive third quarterback. Not wanting to make Russell No. 2 is the reason that hasn?t happened earlier. With NFL rules mandating the third quarterback can only play in the fourth quarter or if the other two are down, Kiffin didn?t want to be in position to have to play Russell yet. None of this will matter if McCown overcomes his latest injury enough for Kiffin to give him the start in Minnesota.
