Penguins captain Sidney Crosby participated in his first full practice since concussion-like symptoms resurfaced in December and there is optimism he'll be back before the playoffs. Crosby insists there still is no timetable on when he'll be cleared to play in a game, but he looked crisp while spending more than an hour on the Consol Energy Center ice. "It's a good step," Crosby said. "Hopefully, I can keep the momentum and get out there soon."
