Garrett Hartley kicked an 18-yard field goal 6:29 into overtime Sunday as the New Orleans Saints remained unbeaten after 12 games with a 33-30 victory over the Washington Redskins. The Saints clinched the National Football Conference South with a far-from-perfect win that shows just how charmed their season is becoming.

Peyton Manning threw one TD pass, Joseph Addai ran for two scores and the Colts spent the second half protecting the lead against the Titans.

Raiders 27, Steelers 24: At Pittsburgh, Louis Murphy caught an 11-yard touchdown pass from Bruce Gradkowski with nine seconds remaining, his second score in the final 5 1/2 minutes as Oakland scored three late touchdowns to deal Pittsburgh its fourth consecutive loss. Dolphins 22, Patriots 21: At Miami, Chad Henne threw for a career-high 335 yards and directed a 51-yard drive for the winning field goal with 1:02 left, and Miami rallied past New England. Eagles 34, Falcons 7: At Atlanta, Michael Vick accounted for a pair of touchdowns on his return to the Georgia Dome_ one running, the other passing _ and basked in the cheers of his former home and Philadelphia thoroughly dominated the short-handed Atlanta. Giants 31, Cowboys 24: At East Rutherford, New Jersey, Brandon Jacobs had the Giants' longest play of the season for just a few minutes, then Domenik Hixon topped it, lifting New York past Dallas. Chargers 30, Browns 23: At Cleveland, LaDainian Tomlinson scored his 150th career TD and stiff-armed Hall of Famer Jim Brown for eighth place on the career rushing list as San Diego won its seventh straight and 15th in a row in December by beating Cleveland. Bengals 23, Lions 13: At Cincinnati, running back Cedric Benson returned from a two-game layoff because of an injured hip and tied the team record with his fifth 100-yard game of the season, setting up Cincinnati's victory over Detroit that had even greater significance for the franchise. Jaguars 23, Texans 18: At Jacksonville, Florida, David Garrard threw two touchdown passes and Josh Scobee kicked three field goals as Jacksonville stayed in the AFC wild-card hunt with a victory over Houston.
