After a mistake by the Dallas offensive line the Giants scored a safety.  Later John Carney nailed a 47-yard field goal to make the score 14-8 for Dallas.  With 2:24 left on the clock Dallas sealed the win with a 38-yard touchdown run by Tashard Choice.  The two-point conversion failed. With the win, Dallas improved to 9-5.
