In the first quarter, the Niners took an early lead with kicker Joe Nedney nailing a 29-yard field goal for the only score of the period.  In the second quarter, the 49ers lost their lead with RB Reggie Bush's 1-yard and 8-yard TD runs.  In the third quarter, San Francisco came close with QB Alex Smith's 48-yard TD pass to WR Antonio Bryant, yet New Orleans gained some distance with kicker John Carney's 19-yard field goal and QB Drew Brees' 5-yard TD pass to Bush.  In the fourth quarter, the Saints wrapped things up with Bush's 10-yard run and Carney's 33-yard field goal.  With their second-straight loss, the 49ers fell to 5-7.
