PHILADELPHIA -- Eagles quarterback Michael Vick described his hamstring injury as a "bad pull" Tuesday and said he was only at "60, 65 percent" last week.

He would not put a percentage on where he is now. He did not go as far as saying he can't play Sunday against the Dallas Cowboys, but he sounded like a man resigned to missing his second consecutive start.

"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."

Nick Foles started Sunday's 31-20 victory in Tampa. Vick took limited practice reps last week. He was active for the game, but would have played only in an emergency situation.

"If I had to go in a game, I could sit in the pocket and throw the football," Vick said. "That's like playing seven-on-seven. But seven-on-seven is kind of unrealistic on Sundays. You've got people coming at you. So being an emergency guy, that's just what I'm going to be, if that's the case."

Vick said he tried a different stretching regimen before the game against the Giants in which he suffered his injury.

"And then I tried to overstride when I was running," Vick said. "I tried to extend too much instead of leaning like I normally run. I understand what I did wrong, and hopefully it won't happen again. That's why it's been so tough. I think I've had only two hamstring injuries, and hamstrings are prevalent for fast guys. I've never really had any."

And with his legs being such a major aspect of his game, Vick said he must be especially "meticulous" in getting back to full strength.
