Hoping to rebound from their tough divisional road loss to the Saints, the Panthers went home for a Week 10 NFC South rematch with the Atlanta Falcons.  Carolina would trail early in the first quarter as Falcons kicker Jason Elam booted a 35-yard field goal, yet the Panthers came right as running back Jonathan Stewart got a 1-yard touchdown run.  Carolina would add to their lead in the second with quarterback Jake Delhomme hooking up with wide receiver Steve Smith on a 4-yard touchdown pass, yet Atlanta would answer with a 1-yard touchdown run from running back Jason Snelling.  The Panthers would close out the half with Delhomme's 4-yard touchdown pass to Smith. In the second half, the Falcons began to erase their deficit as Elam nailed a 24-yard field goal in the third quarter, followed by quarterback Matt Ryan completing a 3-yard touchdown pass to tight end Justin Peelle.  Afterwards, Carolina would pull away as Stewart got a 45-yard touchdown run.
