Penguins center Sidney Crosby has been approved to participate in light workouts. He has been out since Jan. 6 because of a concussion. A source within the organization told the Pittsburgh Tribune-Review that he is cleared for light, off-ice workouts. Crosby has missed nine games after getting hit headfirst into the boards by Tampa Bay defenseman Victor Hedman in a Jan. 5 game. He also absorbed a blindside hit to the head from Capitals forward David Steckel during the Jan. 1 Winter Classic outdoors game.
