PHILADELPHIA - The quarterback section of the Eagles' depth chart currently reads "Michael Vick/Nick Foles."

Coach Chip Kelly has yet to remove the slash.

Kelly declined on Wednesday to name a starter for Friday's preseason opener against New England at Lincoln Financial Field, mainly because he's not putting much emphasis on whether Vick or Foles is lining up behind center Jason Kelce for the first offensive play.

"They are both going to get reps, so whoever takes the first rep, let's not anoint them as anything," Kelly said after Wednesday's joint practice with the Patriots at the NovaCare Complex. "Someone's got to be the first guy, but I wouldn't say that the guy who starts the game is going to be the starter overall or in general as we get going on Sept. 9 (at Washington).

"How do we divvy up Mike's and Nick's snaps? We'll try to make that as even as possible. That's kind of our thought process as we go through this."

Both Vick and Foles have been alternating with the first-team offense throughout training camp. Rookie Matt Barkley, who was hoping to get a shot at competing for the starting job, has been primarily working with the backups.

If Barkley impresses against the Pats, however, the fourth-round draft pick may climb up the depth chart.

"I just want to see which quarterback does the best job of moving the team," Kelly said. "The bottom line is find which quarterback gives us the best opportunity to win. No matter who they're out there with, I want to see them move up and down the field."

Kelly took a chance this offseason by re-signing Vick to a one-year contract rather than releasing him.

So far, it's been worth the gamble. Vick has been the most impressive quarterback in training camp, especially in the last week. The 33-year-old stood out again on Wednesday, hitting wide receiver DeSean Jackson for a 40-yard touchdown against Patriots defensive backs Aqib Talib and Duron Harmon during the live period.

He would appear to have a slight lead in the quarterback race.

"Regardless of who you are out there with, you always want to be at your best and you want to bring out the best of everyone around you," Vick said. "Every time I'm out there, I just try to get the most out of each and every player on this team. That's just the role I've been accustomed to since I came into this league."

Vick's challenge is to stay healthy, which has been a problem since he signed with the Eagles in 2009. Rib injuries and a concussion suffered last season forced him to miss 13 total games over the last three seasons.

He reported to camp this summer in tremendous shape and has been gaining more confidence with Kelly's innovative offense by the day.

"I think I've had a pretty good camp so far," Vick said. "I've done some good things and there are some things I need to work on."

But Foles has also performed well.

Although not as mobile as Vick, the 6-foot-6, 243-pounder has shown poise in the pocket and terrific awareness. The 24-year-old also delivered some nice throws during Wednesday's practice, including a 30-yarder down the sideline to wide receiver Greg Salas against double coverage.

"I'm not really worried about (who starts on Friday)," Foles said Wednesday. "I always play to win when I'm out there. That's my mindset. I'm just going to keep working. I feel like I'm getting a little better every day, and I think our offense is heading in the right direction."

Regardless of which quarterback gets the nod, don't expect any complaints from the other guy.

Vick and Foles have a mutual respect that dates back to last season, when Foles took over for Vick and wound up starting six games. When one is on the field Friday, the other will be supporting him from the sideline.

"If it's me (playing), I know Mike will be cheering me on," Foles said. "And if it's Mike, I know I'll be cheering him on. We're pushing each other every day, but we're also teammates."
