Quarterback Tony Romo had back surgery and will miss the Dallas Cowboys' regular season finale with the NFC East title and a playoff berth on the line.
Coach Jason Garrett said Romo underwent surgery on Friday after consultation with doctors during the week following his injury in a win over Washington.
Kyle Orton will start for the Cowboys in the winner-take-all game against Philadelphia on Sunday.
Romo lost the past two winner-take-all finales - to the New York Giants two years ago and to Washington last season. He also lost to the Eagles in the same situation in 2008.
The Cowboys have missed the last three postseasons.
