Coming off a defensively-strong performance against the Cardinals, the Panthers flew to the Louisiana Superdome for a Week 9 NFC South duel with the undefeated New Orleans Saints.  Carolina got off to a fast start in the first quarter as running back DeAngelo Williams got a 66-yard and a 7-yard touchdown run.  The Saints would get on the board in the second quarter as kicker John Carney made a 23-yard field goal.  The Panthers came right back as kicker John Kasay nailed a 32-yard field goal, but New Orleans would close out the half as Carney booted a 25-yard field goal. In the third quarter, the Saints continued to hack away as running back Pierre Thomas got a 10-yard touchdown run.  Carolina answered with Kasay's 25-yard field goal, but New Orleans would tie the game to end the period as quarterback Drew Brees completed a 54-yard touchdown pass to wide receiver Robert Meachem.  Afterwards, the Saints would pull away in the fourth quarter with Carney's 40-yard field goal, followed by defensive tackle Anthony Hargrove forcing a fumble from Williams and returning it 1 yard for a touchdown.
