The Lions placed linebacker Alex Lewis on injured reserve Monday with a torn pectoral muscle and signed linebacker Darnell Bing off the practice squad.

Lewis suffered the injury trying to tackle Cadillac Williams in the second half of a Nov. 23 loss to Tampa Bay. He said last week he hoped to return for the final three games.

The Lions should get some good news on the injury front later this week. Cornerback Keith Smith is expected to return after missing the past four games with a groin pull, and defensive end Dewayne White might be back after missing four weeks with a calf injury.

No word on Daunte Culpepper's MRI yet, and we won't know until Dan Orlovsky tries throwing Wednesday whether he'll be available for Sunday's game at Indianapolis.
