Coming off their west coast win over the Chargers, the Falcons flew to the Louisiana Superdome for a Week 14 NFC South rematch with the New Orleans Saints. Atlanta trailed fairly early in the first quarter as Saints quarterback Drew Brees completed a 5-yard touchdown pass to RB Reggie Bush. In the second quarter, the Falcons continued to trail as kicker Garrett Hartley got a 26-yard field goal. Atlanta would respond RB Michael Turner getting a 5-yard TD run, yet Hartley gave New Orleans a 46-yard field goal.  The Falcons struck back with rookie quarterback Matt Ryan completing a 2-yard TD pass to WR Brian Finneran, but the Saints closed out the half with Hartley's 25-yard field goal. Atlanta would get the third quarter's only points as kicker Jason Elam nailed a 23-yard field goal.  In the fourth quarter, New Orleans tried to pull away as Brees completed a 7-yard touchdown pass to RB Pierre Thomas, yet their 2-point conversion attempt failed.  The Falcons would then take the lead as Ryan got a 12-yard touchdown run, followed by a 2-point pass to wide receiver Michael Jenkins.  However, the Saints got the last laugh as Thomas got a 5-yard TD run.
