Coming off their Sunday night home win over the Bears, the Falcons flew to Cowboys Stadium for a Week 7 duel with the Dallas Cowboys.  In the first quarter, Atlanta took flight as quarterback Matt Ryan hooked up with wide receiver Roddy White on a 4-yard touchdown pass.  The Cowboys would take the lead in the second quarter with kicker Nick Folk nailing a 38-yard field goal, followed by quarterback Tony Romo completing a 59-yard touchdown pass to wide receiver Miles Austin and a 5-yard touchdown pass to wide receiver Patrick Crayton. In the third quarter, the Falcons answered with running back Michael Turner got a 2-yard touchdown.  However, Dallas came right back with Romo finding Austin again on a 22-yard touchdown pass.  The Cowboys would increase their lead in the fourth quarter with Folk booting a 46-yard field goal, followed by Crayton returning a punt 73 yards for a touchdown.  Atlanta tried to come back as Ryan completed a 30-yard touchdown pass to wide receiver Eric Weems, but the Cowboys closed out the game with Folk's 34-yard field goal.
