Irving, TX (SportsNetwork.com) - With Tony Romo nursing a herniated disc in his back, Kyle Orton is on track to start Sunday night's game regular season finale for the Dallas Cowboys against the Philadelphia Eagles in a winner- take-all contest for the NFC East title.
Although the Cowboys haven't ruled Romo out of Dallas' home finale, head coach Jason Garrett said Wednesday Romo "certainly doesn't seem overly comfortable."
Orton, who took practice reps with the first team offense Wednesday, hasn't started a game since Week 17 of the 2011 season when he was with Kansas City. That was a 7-3 victory over the Denver Broncos.
"There's no doubt I'm excited," Orton said. "We'll see how Tony heals up. He's a great quarterback, he's had a great year and I know he wants to finish this thing out. But as a backup, that's your job to be ready to go whenever it is. I think the guys have got a lot of confidence in me, I know I've got a lot of confidence in myself, and I'm excited to play.
As for Romo, he wasn't seen at practice Wednesday.
"He's trying to do everything he can to try and get himself back," Garrett said. "He's a tough guy, as you saw the other day. We'll see how he does.
"Tony, we're checking day by day. I saw him this morning and he's still working his way through this thing."
As a stop-gap measure, the Cowboys finalized a deal with 41-year-old signal- caller Jon Kitna Wednesday. Kitna last played in the NFL with the Cowboys two seasons ago.
It turns out Kitna called Garrett about a possible return to the team when Romo's injury was revealed.
"I told Jason if he needed somebody to come in that could call a play, be able to pull a play off if a bad situation happened, I'd be willing to do that," Kitna said. "I wasn't staying in shape thinking I'd get another shot, that's for sure."
Kitna has played 15 seasons in the NFL and started nine games for Dallas in 2010. He appeared in three games in relief the next season before retiring at the end of the year. Kitna, who officially joined the Cowboys Wednesday, is the football coach and math teacher at Lincoln High School in Tacoma.
Also on the injury front, Cowboys linebacker Sean Lee (neck) didn't practice Wednesday. He will reportedly be out for the contest. He hasn't played since Dec. 9 against the Bears.
