The Saints played the Thanksgiving Day game at Cowboys Stadium for an NFC duel against the Cowboys. The Saints commanded the first quarter with RB Chris Ivory getting a 3-yard TD run, followed by kicker Garrett Hartley getting a 50-yard field goal, and then by Ivory making a 6-yard TD run. The lead was narrowed as kicker David Buehler got a 21-yard field goal, but the Saints replied as Hartley nailed a 45-yard field goal. The lead was narrowed again as Buehler hit a 53-yard field goal, followed by Miles Austin getting a 60-yard TD run. The Saints scored with Hartley making a 28-yard field goal, but fell behind with Marion Barber and Tashard Choice getting a 1-yard TD run. The Saints, down 27-23, were well on their way to defeat when John Kitna hit Austin with a long-gainer, but safety Malcolm Jenkins stripped Roy Williams and recovered at the New Orleans 11, enabling the Saints to pull out the win five plays later, with QB Drew Brees completing a 12-yard TD pass to WR Lance Moore, completing an 89-yard drive.
