The Texans were forced to punt on their next possession and Vick drove the Eagles 72 yards in eight plays, hitting Owen Schmitt with a 5-yard scoring pass that all but wrapped up the game with 4:18 remaining.
Philadelphia improved to 8-4 and took a half game lead at the top of the NFC East over the New York Giants. New York will host Washington Sunday.
