In front of a national audience, the Eagles traveled to Foxboro as 22-point underdogs in their matchup against the 10-0 New England Patriots - the first meeting of the teams since Super Bowl XXXIX. The Eagles started A. J. Feeley due to McNabb's injury, and Asante Samuel picked off a Feeley pass and returned it 40 yards for a touchdown on the third play of the game. The Eagles responded with a 14-play drive, capped by a one-yard diving touchdown by Brian Westbrook. Tom Brady finally got a chance late in the first quarter, and marched New England down the field before Heath Evans took it in from a yard out to make it 14-7 Patriots. However, Feeley answered back with a 28-yard touchdown to third receiver Greg Lewis. Andy Reid then tried an onside kick. Hank Baskett recovered the ball, but the Eagles were forced to punt. In a ten-play drive of all pass attempts, the Patriots had first-and-goal, but settled for a field goal to take a 17-14 lead. Feeley found Lewis again on the next series, this time an 18-yard strike with three minutes left in the half, giving Philadelphia the lead. Brady connected with Jabar Gaffney to retake the lead 24-21 with seconds left in the half. A long drive by New England in the third quarter resulted in a missed field goal, and Feeley responded with a touchdown drive capped by an eight-yard reception in the end zone by Reggie Brown and the Eagles took a 28-24 lead as the game moved into the final quarter. Laurence Maroney scored from four yards out midway through the fourth as the Patriots went back on top 31-28. Feeley took the Eagles to within field goal range, but was picked off trying for a touchdown and the Patriots' perfect season survived. Feeley had 345 passing yards and three touchdowns, but his three interceptions were costly. Westbrook had 92 all-purpose yards and a touchdown, while Greg Lewis racked up a surprising 88 receiving yards and two touchdowns. The loss drops the Eagles to 5-6.
