Why one practice might have triggered some hope in the down-but-not-out Penguins

PHILADELPHIA — The Pittsburgh Penguins were in the late stages of practice on Friday at the Flyers Training Center when an errant puck hit Sidney Crosby in the back of his head.This could have been great cause for alarm, but instead, Crosby and everyone else started laughing. Justin Brazeau skated over to the Penguins captain and rubbed the back of his noggin for good measure.Advertisement
