Giants defensive end Justin Tuck is concerned about the lingering pain in his neck, which has created questions about his availability for Sunday's game against the Redskins. Tuck is still feeling the effects of a stinger he suffered in a preseason game against the Jets on Aug. 29. After going through a limited practice on Wednesday, Tuck did not practice on Thursday. "I am concerned but I am not panicked," Tuck said. "It is getting better but just not as fast as I want it to." "We are going to do what's best," he added. "You don't want to go out there and lose a season off of one game. But if I'm ready to play I will definitely strap it up."
