Goaltender Corey Crawford was a full participant in the Blackhawks' practice Thursday and appeared fine in the dressing room afterward.

Apparently, he wasn't.

Crawford was not on the ice for the Hawks' morning skate Friday before their game against the Sharks at the United Center and afterward coach Joel Quenneville said the goalie was "day-to-day" with an upper-body injury.

"He didn't feel great after (Thursday's) practice," Quenneville said. "That's where he's at. I don't know if it was a defining blow."

Late in the Hawks' game against the Ducks on Tuesday night, Crawford took a knee to the head from Bobby Ryan during a collision in the crease but finished the contest. Crawford then participated in the Hawks' practice Thursday but afterward Quenneville said Ray Emery would get the start against the Sharks.

The Hawks recalled Henrik Karlsson from Rockford of the AHL on Friday and he served as Emery's backup against the Sharks.
