Corey Crawford gave his teammates and Blackhawks fans quite a scare when he stumbled out of the crease and skated to the tunnel hunched over following the first period Thursday night in St. Louis. Ray Emery came in and completed the 3-0 shutout of the Blues, but Crawford's status was clearly cause for concern.

But Crawford was back on the ice at the United Center on Friday morning, and will be dressed as Emery's backup tonight as the Hawks host the Columbus Blue Jackets.

"Corey's fine," Hawks coach Joel Quenneville said.

Quenneville declined to specify what was ailing Crawford -- he did say it wasn't related to the upper-body injury that sidelined him for four games in February. But whatever it was, it didn't last long.

"He got through it," Quenneville said. "He didn't seem too bad after the game. He was fine this morning. He's good."

Emery made 14 stops in Crawford's place, though Crawford got credited with the win. Emery is 8-0-0 on the season, and earned the NHL's third star of the month for going 7-0-0 with a 1.66 goals-against average and a .941 save percentage.

"Congratulations to Ray," Quenneville said. "Nice job. He had some consecutive starts here and he's doing the job. The guys have confidence with him."
