Trying to snap a two-game skid, the Falcons flew to the Louisiana Superdome for a Week 7 divisional duel with the New Orleans Saints. Due to QB Joey Harrington's ineffectiveness from last week's loss to the Giants, QB Byron Leftwich was given the start. In the first quarter, Atlanta trailed early as Saints QB Drew Brees completed a 37-yard TD pass to WR Devery Henderson. The Falcons responded with former Saints kicker Morten Andersen's 38-yard field goal. In the second quarter, Atlanta began to play well as Andersen got a 33-yard field goal, while Leftwich completed a 9-yard TD pass to WR Roddy White. In the third quarter, New Orleans retook the lead with RB Pierre Thomas getting a 24-yard TD run. On the Falcons' next possession, Leftwich's left leg got injured during a sack by Saints DE Will Smith. Harrington took over for the rest of the game. In the fourth quarter, Andersen gave Atlanta a 21-yard field goal. The Saints sealed the win with Brees hooking up with RB Reggie Bush on a 4-yard TD pass, along with Bush's 2-point conversion run. With their third-straight loss, the Falcons entered their bye week at 1-6.
