Corey Crawford injured vs. Blues

Chicago Blackhawks goaltender Corey Crawford left Thursday's 3-0 victory over the St. Louis Blues after the first period and is considered day to day with an upper-body injury, Blackhawks coach Joel Quenneville said.

Crawford appeared to stumble and nearly fall forward as he came out of the net at the end of the first period. He was replaced by Ray Emery to start the second period.

"I don't think there was a defining moment or blow," Quenneville said.

Crawford missed four games because of an upper-body injury earlier in the month, but Quenneville said this injury is not related. He was making his second start Thursday since the injury.

Crawford stopped all six shots he faced in the first period. He entered Thursday's game with an 8-0-3 record, a 1.50 goals-against average and a .941 save percentage.

Emery made 15 shots over the second and third periods on Thursday, and the Blackhawks recorded their third shutout of the season.

Quenneville said the Hawks would determine Friday if they need to call up another goaltender.
