Stewart leaves with head injury

EAST RUTHERFORD, N.J. -- Something to keep an eye on as the game goes on. Carolina running back Jonathan Stewart suffered a head injury in the second quarter and has yet to return.

Stewart's still being examined by medical personnel and team officials just said it's questionable if he'll be able to return tonight. The Panthers pride themselves on dividing the load between DeAngelo Williams and Stewart and generally are careful not to overuse Williams. If Stewart can't come back, look for a healthy dose of playing time from backup running back Nick Goings in the second half.
