Backup quarterback Kyle Orton, subbing for injured Tony Romo, threw an interception with 1:43 left, clinching Philadelphia's 24-22 NFC East-clinching victory over the Cowboys before a sellout crowd of 91,166.
The game was closer and more thrilling than expected, but result was all-too-familiar for the Cowboys. For the fourth straight year, they'll watch the playoffs from home.
For the third straight year, Dallas lost a win-or-stay home regular-season finale and finished 8-8. Philadelphia, not Dallas, is the NFC's No. 3 seed and will host New Orleans next Saturday in the first round of the playoffs.
The Cowboys pulled within two points with 3:50 remaining when, on fourth and nine, Kyle Orton found Dez Bryant over the middle for a 32-yard touchdown pass.
Orton's 2-point conversion pass attempt for Bryant in the left corner of the end zone, however, was broken up by Philadelphia's Cary Williams.
The Cowboys forced the Eagles to punt and took over on their 32 with 1:49 left, but on the next play Orton threw behind Miles Austin and the pass was intercepted by Brandon Boykin.
Even though Jones has emphasized several times in recent weeks that coach Jason Garrett will return next season, the Cowboys enter an offseason of uncertainty, with many of their core players in their 30s.
The questions start with Romo, who was at home Sunday, recovering from Friday back surgery for what sources said was a herniated disc.
