The Redskins retook the lead with Jason Campbell connecting with Devin Thomas for a 10-yard touchdown. With the Saints now down 17-10, Brees and the Saints attempted to drive the field.

The Saints completed the comeback with Garrett Hartley's 18-yard field goal for the first lead in the game and the win 33-30 in overtime.
