Add Clay Matthews to Packers' injury list

GREEN BAY, Wis. -- Man. The latest Green Bay Packers injury to report is linebacker Clay Matthews, who limped off the field here in the third quarter because of a hamstring injury. His return is questionable.

Matthews appeared to have been playing with the injury for a good portion of the game. On the play before he left, Cardinals quarterback John Skelton broke away from what appeared to be a sack.
