Ravens defense is extremely banged up

BALTIMORE -- The Baltimore Ravens have been playing this season without NFL Defensive Player of the Year Terrell Suggs. Now, after Sunday's 31-29 victory over the Dallas Cowboys, the injury list for Baltimore's defense is growing longer and more serious.

Cornerback Lardarius Webb, linebacker Ray Lewis and defensive tackle Haloti Ngata all left the game for extended periods with injuries.

The most serious is Webb, the Ravens' top cornerback, who has a "potential ACL" injury, according to coach John Harbaugh. He banged knees with Dallas receiver Dez Bryant late in the first quarter and needed help to get off the field. It now appears that Webb will be lost for the season. Jimmy Smith, a 2011 first-round pick, is expected to replace Webb.

"Lardarius Webb does not look good right now," Harbaugh said. "We've got a problem there."

Lewis, who has received criticism for declining play, wasn't on the field when the Ravens defense was trying to make winning stands on the final two drives. The Ravens have classified it as a triceps injury. Lewis didn't speak to reporters after the game because he was undergoing treatment and left immediately for tests.

"I don't think it's real bad," Harbaugh said.

Ngata tweaked his knee early in the game but he later returned. He didn't move around well when he was in the game.

The Ravens' defense gave up 481 yards and 29 points to the Cowboys on Sunday, its second-highest totals of the season.
