Redskins defensive lineman Adam Carriker was injured early in Washington's Sunday afternoon matchup with the St. Louis Rams, and it appears his return to the contest is questionable. Via the team's official twitter feed:

While engaged with a St. Louis offensive lineman, Carriker had his knee rolled up on. He needed assistance to get off the field, and was putting very little weight on the knee.

Washington currently leads the game 7-3 in the first quarter, having scored a defensive touchdown on the Rams' first offensive play of the contest.
