With their Super Bowl title to defend, the Saints began their season at home in the annual Kickoff Game against the Minnesota Vikings, in a rematch of last season's NFC Championship Game.  New Orleans would strike first in the opening quarter with quarterback Drew Brees hooking up with wide receiver Devery Henderson on a 29-yard touchdown pass.  The Vikings would take the lead in the second quarter as kicker Ryan Longwell made a 41-yard field goal, followed by quarterback Brett Favre's 20-yard touchdown pass to tight end Visanthe Shiancoe (with a blocked PAT). In the third quarter, the Saints would regain the lead with a 1-yard touchdown run from running back Pierre Thomas.
