context:  Now functioning as a spoiler, the Eagles traveled to face the New Orleans Saints at the Superdome - site of two losses in 2006, including one in the NFC Divisional Playoffs. The first quarter would be a shootout, with the teams combined for 5 touchdowns and over 300 yards of offense. On the third play from scrimmage, Donovan McNabb scrambled for a 40-yard gain, but fumbled, only to have the ball recovered in the end zone for a touchdown by receiver Kevin Curtis. A 52-yard bomb to wideout Devery Henderson keyed a four-play drive ending in a New Orleans touchdown by running back Aaron Stecker. McNabb's second fumble was recovered by New Orleans in Philadelphia territory, setting up another short touchdown for Stecker. The Eagles offense again moved the ball and Correll Buckhalter scored on a 20-yard scamper and the game was tied 14-14. On Philadelphia's next drive, McNabb found the open Reggie Brown for a 31-yard touchdown pass and a Philadelphia lead. In the second quarter, David Akers and Martin Gramatica traded field goals as the offenses settled down. The Saints had 2nd-and-goal from the 1-yard line on their opening drive of the second half, but the Eagles' defense stepped up with another big goal line stand and the seven-point lead was preserved. McNabb then led the Eagles on a 98-yard, seven-minute drive that ended in a 9-yard touchdown pass to Greg Lewis. The Saints answered with two field goals to get within eight at 31-23, but a McNabb to Curtis touchdown pass late in the fourth quarter wrapped things up for Philadelphia. McNabb looked mobile and was effective, throwing for three scores and 263 yards. Brian Westbrook had 100 rushing yards, while Curtis had 78 receiving yards, a touchdown reception, and a fumble recovery for a touchdown. The second straight win raised the Eagles' record to 7-8 and gave them a chance to finish .500 with a win over the Buffalo Bills.
