The Baltimore Ravens will likely be without talented defensive standouts Ray Lewis and Ed Reed for this weeks big game against the Pittsburgh Steelers.

Lewis suffered a strained right hamstring during the Bears game this past Sunday. Linebacker Bart Scott will move into a linebacking position to replace Lewis if he can't go against the Steelers.

Reed was injured during the Browns game two weeks ago, and did not play against the Bears. Defensive back Chad Allen will replace Reed.

With the Ravens offensive struggles this year, they can't afford to be losing players on defense.
