Passage: Hoping to recover from their home loss to the Ravens, the Cowboys closed out their regular season at Lincoln Financial Field in a crucial Week 17 NFC East rematch with the Philadelphia Eagles, with a playoff berth on the line. Dallas trailed early in the first quarter as Eagles David Akers got a 40-yard field goal. Dallas would respond with kicker Nick Folk getting a 37-yard field goal. However, in the second quarter, Philadelphia would take a huge lead as quarterback Donovan McNabb would get a 1-yard touchdown run and complete a 4-yard touchdown pass to running back Correll Buckhalter, along with a 1-yard touchdown pass to tight end Brent Celek. Afterwards, the Eagles would close out the half with a 50-yard field goal from Akers. In the third quarter, the Cowboys' playoff hopes continued to take a beating as defensive end Chris Clemons returned a fumble 73 yards for a touchdown, while cornerback Joselio Hanson returned another fumble 96 yards for a touchdown. Philadelphia would close out the period with Akers' 41-yard field goal. In the fourth quarter, Dallas tried to rally but only managed to score a 42-yard field goal.
