Kelly again implied yesterday that he would not play Vick until he was 100 percent healthy. But anyone who has ever suffered through any degree of hamstring pull will tell you that you can never quite tell when 100 percent is reached. It might feel fine running around on it, and then suddenly pop - you're right back where you were, or worse. Or it might feel 100 percent one day, you go to sleep, and there it is again when you awaken.
