PHILADELPHIA (CBS) —  While all signs point towards Michael Vick starting against the Giants on Sunday, the Eagles quarterback wasn’t about to make any guarantees.

Vick took snaps with the first unit at Tuesday’s practice, but when pressed by reporters afterwards about his status, Vick did not say if he would play on Sunday.

“I guess you can’t get it out of me right now,” said a smiling Vick.  “We’ll see.  I’m optimistic about it.”

Vick is still recovering from a hamstring injury he suffered against the Giants on October 6.  He believes he would be able to play even if he isn’t at 100%, but Vick says he will play the same way he always plays even if he isn’t fully recovered.

“I’m giving it everything I’ve got,” Vick said.  “No holding back.  I’ll never go out into a game and limit myself as to what I can do.  I’m excited about the opportunity to play this week if that’s what I’m called for.”

Nick Foles struggled before leaving Sunday’s game with a concussion.  He did not participate in practice, as Matt Barkley and G.J. Kinne took snaps behind Vick.  DeSean Jackson says the players much take the same approach no matter who is playing quarterback.

“You try to go out there and really not get into what’s different about two guys you have throwing to you,” said Jackson.  “You have to go out there and make plays.  Judging the quarterbacks is not my option.  I have to make plays.”

The Eagles still have more practice time during the week, and an answer as to who will play quarterback could come well before Sunday.  Vick is doing everything he can to make the decision an easy one.

“I’m working hard every day,” Vick said.  “I’m trying to do everything I can to get out there.  I’m just very excited about playing with these guys this week and seeing if I can get myself back to 100%.”
