Coming off their road win over the Bears, the Giants flew to Lincoln Financial Field for a Week 14 NFC East rematch with the Philadelphia Eagles.  In the first quarter, New York trailed early as Eagles QB Donovan McNabb completed an 18-yard TD pass to RB Brian Westbrook for the only score of the period.  In the second quarter, the Giants started to draw close as kicker Lawrence Tynes managed to get a 19-yard and a 23-yard field goal. In the third quarter, Philadelphia responded with kicker David Akers getting a 29-yard field goal. Afterwards, New York took the lead with QB Eli Manning completing a 20-yard TD pass to WR Plaxico Burress, along with Tynes kicking a 23-yard field goal. In the fourth quarter, the Eagles tried to come back as Akers nailed a 39-yard field goal. In the final seconds, Philadelphia had a chance to tie the game and force overtime. Fortunately for the Giants, Akers missed a 57-yard field goal off the right upright with 1 second left to preserve the victory and the season-sweep. This also marked the first time since their Super Bowl XXXV appearance of 2000 that New York had won 6-straight road games.
