Hoping to beat the defending Super Bowl champs, the Ravens returned home. New Orleans struck first with an 18-yard pass from Drew Brees to Jimmy Graham, but Baltimore quickly answered with Flacco throwing a 34-yard pass to Ed Dickson. The Ravens then followed with two touchdowns, both by Ray Rice, one rushing (10yards) and one passing (17yards), to bring the score up 21-7. At the close of the half, the Saints scored on a 1-yard pass to Graham to bring the halftime score to 21-14. The Saints kicked a field goal to enter the third quarter to make it 21-17, but the Ravens quickly answered that with a field goal to make it 24-17. The Saints tied it in the fourth quarter on a 15-yard touchdown pass to Lance Moore in the corner of the end zone, a play that was challenged by Baltimore but not overturned. The Ravens managed to get ahead with a Billy Cundiff field goal with 10:03 remaining 27-24.The Saints had the ball in the final minutes backed up near their own end zone when Drew Brees threw an interception to Cory Redding to give Baltimore a chance to run off the clock. Though there was not enough time to run off the entire clock, Baltimore managed to leave just 9seconds as they kicked a field goal to make it 30-24. The Saints had one last chance on their kickoff return in which they pitched it around in hopes of a touchdown, but they were stopped. They were also called for a moot penalty for a forward pass that would have rendered any drive at this point null. Overall, the game was highlighted by Ray Rice's 153yards rushing and two touchdowns, Billy Cundiff's two field goals, and the Redding interception that virtually ended the game. With the win, the Ravens went to 10-4, nearly clinching a playoff berth.
