Eagles quarterback Michael Vick, coming off a concussion and a bruised non-throwing hand, has vowed to play against the 49ers on Sunday. However, San Francisco coach Jim Harbaugh suggested otherwise in a rare moment of humor. "He's a great player," Harbaugh said. "I think with the (concussion) he had two weeks ago, with the hand injury this week, it would probably be the prudent thing to rest him for a week."
