Kyle Orton confident if needed vs. Eagles

IRVING, Texas -- Kyle Orton took all of the first-team snaps in Wednesday's practice as the Dallas Cowboys began their on-field preparation for Sunday's game against the Philadelphia Eagles.

With Tony Romo likely to miss the NFC East title game with a back injury, Orton would make his first start since the 2011 season finale while he was with the Kansas City Chiefs.

"We'll see how Tony heals up," Orton said. "He's a great quarterback. He's had a great year and I know he wants to finish this thing out. But as the backup that's your job to be ready to go whenever it is. I think the guys got a lot of confidence in me. I know I've got a lot of confidence in myself and I'm excited to play."

Orton has a 35-34 career record as a starter for the Chiefs, Denver Broncos and Chicago Bears, but he has thrown just 15 passes in the last two seasons and only five this year.

While Romo might be able to create more opportunities on his own, Orton said he would rely on the weapons around him to make plays.

"I fall back on my experience," Orton said. "I've played a lot of games in this league and had some success so just excited with the group of guys I've got around me. I don't really feel like I've got to go out and do too much. Get the play to the playmakers. Get the ball to (DeMarco Murray, Jason Witten and Dez Bryant) and let those guys go to work."

Orton also talked about what kind of challenges he faces after not playing for most of the season: "Physically nothing. Just kind of ease your way into the game a little bit. Just get the ball to the guys that do great things with it and we've got plenty of those guys. I've been here for a couple of years so timing is not too big of an issue and thought we went out and had a good practice [Wednesday]."

Orton took all of the first-team snaps in the offseason as Romo recovered from surgery to remove a cyst from his back in April. Romo did not practice with the team until the first day of training camp in Oxnard, Calif.

Orton said he did not take a first-team rep in practice the entire season until Wednesday.

"Anytime you're a backup, all the reps you can get with the guys are important," Orton said. "I was kind of fortunate to get a lot of the reps during OTAs. Now that was a long time ago, but I've practiced hard throughout the whole year. I really feel like my game is in a great spot right now and I'm really confident heading into the week."
