Jon Kitna will be the starting quarterback for the Dallas Cowboys in their finale against the Eagles on Sunday if his strained abdominal muscle heals enough.

It's not likely, though, so second-year backup Stephen McGee probably will make his first career start in the 4:15 p.m. game at Lincoln Financial Field.

"We have to see what Jon's availability is throughout the practice week and see what he is able to do," interim coach Jason Garrett said yesterday. "Can he play? Can he practice well enough to play in this game on Sunday? So that's the No. 1 consideration. If he's not able to do that, we will play Stephen. But if he's able to do that, Jon will be our quarterback."

The Cowboys believe an injured Kitna would give them a better chance to beat the Eagles than a healthy McGee.

Kitna has gone 4-5 since replacing Tony Romo and has been hailed for his leadership. His stats are on par with Romo's.

But Kitna is 38. The Cowboys already are planning on him being Romo's backup next season. So why not start McGee against the Eagles no matter what, just to find out what they have - especially since Kitna certainly won't be at full strength?

"There's probably a lot of different reasons," Garrett said. "We just feel like it's best to give Jon a chance to come back and play if he is healthy enough to do it."

McGee made his NFL debut Saturday night after Kitna was hurt during the second quarter against Arizona. He rallied the Cowboys from an 11-point deficit to a late lead, only to see the defense blow it in the final seconds. He completed 11 of 17 passes and didn't have any turnovers.

His biggest concern was not fumbling his first snap. The more he played, the better he felt. To appreciate how much of a step up in competition this was, he hadn't played a game that counted since he was at Texas A & M, and he had never thrown to Jason Witten and Miles Austin.

He'd had only three series with the first-team offense, despite being the No. 2 guy the past 9 weeks.

"Being out there and playing, getting those snaps, those are priceless, a confidence boost," McGee said. "Hey, I've got that out of the way. I've taken snaps. I've played. There are a lot of plays from that game I can draw from and use this week to really focus on and get better."

Dallas added another quarterback yesterday, signing Chris Greisen to the practice squad. Greisen, 34, has never taken a snap in the NFL despite being Arizona's No. 3 quarterback from 1999-2001.

In other Cowboys news, team owner Jerry Jones said he has been refining his list of coaching candidates and it includes fewer than the 10 he interviewed in 2007 when he hired Wade Phillips. He said he has not contacted any. Garrett seems to be near the top of the list.
