An injury to Corey Crawford, which looked very bad at first, might not be that after all.Crawford was injured with six minutes remaining in the first period. He struggled to move laterally after a right-pad save on Marcel Goc’s shot, and play was halted. Crawford, with the help of a trainer, headed to the locker room. As bad as Crawford’s injury looked originally, coach Joel Quenneville sounded optimistic about the goaltender. “I haven’t talked to the docs yet, but I don’t think it’s too serious,” he said. “But when it’s a goalie, it’s a little more serious than other players because of how important he is to the team. We’ll have a better assessment tomorrow, but we’re thinking along those lines (of prognosis).”
