While Eagles head coach Chip Kelly has yet to decide who his starting quarterback will be on Sunday, Nick Foles got all the first-team snaps Tuesday, which was not a surprise.

"Coach Kelly will address those issues about who the quarterback is when both of them are healthy," said Eagles offensive coordinator Pat Shurmur.  "At this point we will go with Nick and then when Mike's healthy then we'll have that discussion."

Speaking Tuesday after practice, Michael Vick said he still feels his hamstring injury "whenever he tries to burst," and that "it was a pretty bad pull."  Remember this injury is to Vick's left hamstring, which means its also the leg he must push off with when attempting to throw the ball.

"I feel it getting better," Vick said. "It's just when I try to burst, that knot is still there. I think another week of rehab can put me in position where I can start gaining some confidence in it and doing things I normally do. ... It can be re-aggravated quickly. Because mine is up so high, and the way I run, I've got to take precautions. I can't overdo it. If I do, it can be another two to three weeks."

The criteria of when Vick might return, remains; is he healthy enough to play and next which quarterback gives the team the best chance to win.  Vick is entering the second week of limited practice after he injured his hamstring running out-of-bounds during the Giants game.  Meanwhile, Foles performed nearly flawlessly in the week six win at Tampa, but both guys have been effective, the team has generated over 400 yards of offense in all six games this season.

The fact that Vick is not practicing yet with the first team and rookie Matt Barkely is taking the second team snaps shows that Foles will play this week is almost a certainty. Vick's hamstring was a concern last week when he was active, but listed as the number three quarterback.

The bottom line is this - Vick is getting better, but he isn't there yet.  One issue is when dealing with a hamstring injury, it is very easy to re-aggravate and re-injury it.  So when you have the ability to turn to a guy like Foles, there is no reason to rush Vick back.

"I think they are both very fine quarterbacks and when you look at our three victories, they contributed equally." explained Shurmur.  "And they do different things well.  And they can both be very, very effective and efficient in our offense."

In other injury news, left tackle Jason Peters did not practice Tuesday, he's expected to practice in full Wednesday and shouldn't be in any danger of missing Sunday's matchup with the Cowboys.

Safety Patrick Chung did not practice Tuesday, his absence attributed to a nerve issue in his shoulder.  It's becoming clear that Chung's injury is more serious than initially thought. He returned last week after missing the last two games, but was limited to just 12 snaps.

Tight end Zach Ertz is now listed as a co-starter with Brent Celek on the Eagles official depth chart.  The second-round rookie played on a season-high 42 snaps against the Bucs and saw six targets. Coach Chip Kelly said the Tampa heat was the reason Brent Celek's snaps decreased, not sure I am buying that - we'll see this week against a beatable Cowboys defense.
