"Derek Anderson will start at quarterback on Saturday night in Chicago.

Coach Ken Whisenhunt said he was disappointed in the offensive production in the first two preseason games.

"I don't think we performed the way we want to perform on offense this preseason and we're going to look at a number of different players in different spots," Whisenhunt said.

Matt Leinart, who had been the starter, will play the second quarter and start the second half."
