ALAMEDA, Calif. -- Marques Tuiasosopo probably will get his shot as Oakland's starting quarterback this week. Coach Norv Turner is leaning toward demoting the struggling Kerry Collins and plans to make his final decision before the Raiders take the practice field Wednesday to prepare for the lowly New York Jets -- though it sure seems Turner has all but made up his mind. The coach already spoke to Collins about the potential change for Sunday's road game. "I wouldn't have brought it up if it wasn't something we're considering strongly," Turner said Monday on the heels of the Raiders' second straight defeat and fourth loss in five games, 34-10 at San Diego. "We're going to look at the quarterback situation and say, 'Hey, is it time to look at Tui?' With his mobility, would that help us?"
