Michael Vick needs another week of rehab on his injured hamstring.
Vick said he was only at "60, 65 percent" last week.
Nick Foles is expected to start in Week 7 against the Dallas Cowboys.
"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."
