Patriots' Danny Amendola leaves game with apparent head injury

Tom Brady lost one of his top receivers during Sunday's game against the Cincinnati Bengals, as Danny Amendola left in the second quarter with an apparent head injury after taking a hit from Bengals safety Reggie Nelson.

Amendola headed to the locker room, and has a history of concussions.

Off to a slow start, Amendola has only three catches for 16 yards this season.
