Bears safety Danieal Manning did some warming up with his teammates.

But he will not play tonight, according to a source with knowledge of the situation. It's a precautionary move, since Manning missed a couple of practices last week with a hamstring injury.

Craig Steltz is expected to start opposite Chris Harris. But rookie Major Wright surely will also see significant playing time.

Manning is currently listed atop the depth chart at strong safety.

He started 10 games last season.
