Coming off their win over the Dolphins, the Falcons stayed at home, donned their throwback uniforms, and prepared for a Week 2 NFC South showdown against the Carolina Panthers.  Atlanta would trail early in the first quarter as Panthers kicker John Kasay got a 38-yard field goal.  Afterwards, the Falcons would answer with quarterback Matt Ryan completing a 24-yard touchdown pass to tight end Tony Gonzalez.  In the second quarter, Carolina would reply with running back DeAngelo Williams getting a 3-yard touchdown run.  Atlanta would strike back as Ryan completed a 10-yard touchdown pass to fullback Jason Snelling.  The Panthers would creep close as Kasay nailed a 50-yard field goal, yet the Falcons would increase their lead prior to halftime as Ryan completed a 7-yard touchdown pass to wide receiver Roddy White.  After a scoreless third quarter, Atlanta would get some necessary distance from Carolina as running back Michael Turner got a 1-yard touchdown run.  Afterwards, Carolina mustered an 11-yard touchdown pass from quarterback Jake Delhomme to tight end Dante Rosario. On another Panthers possession, Delhomme threw an interception to cornerback Chris Houston. After yet another possession, with time running out, the Panthers tried to rally as Delhomme threw a deep desperation pass, but it resulted incomplete as cornerback Brent Grimes batted it down.
