Corey Crawford suffered an injury late in the first period of the Blackhawks' Sunday-night game against the Panthers at the United Center.
Crawford made a stop on a Marcel Goc shot with 6:38 remaining in the first period. But when he went to push off his left leg to move right, he couldn't. Officials stopped the clock with 6:15 remaining, and Crawford was helped off by a trainer.
Antti Raanta came in to relieve. Crawford's status wasn't immediately known.
