[Update: Cox has since returned.]
Rookie defensive tackle Fletcher Cox left the game in the first half against the Cardinals because of migraine headache. His return is questionable.
Cox played more snaps than any other defensive lineman against the Ravens, and has been on the field more than any other defensive tackle for Jim Washburn through two games.
The first-round pick has had an immediate impact for the Eagles. He entered the game with seven tackles and a sack on the young season.
Linebacker Akeem Jordan suffered a hamstring injury and did not return.
