"I was at a concert the other day and was on the way out and missed a step," Crawford said. "I didn't think it was that bad. I got up the next day, and it was worse than I thought. I'm pretty embarrassed about it, frustrated. Things were going really well. Right now, I'm just thinking about trying to get back as quickly as possible and make sure I'm right back where I was when I left off."

Crawford wouldn't disclose any other details about the accident, including whether he broke anything or if alcohol was involved. He was wearing a walking boot on his left foot.

According to a source, Crawford attended a Rise Against concert at the House of Blues Chicago on Monday night.

Crawford is 12-5-1 with a 1.87 goals-against average and .929 save percentage this season. He ranks third in the NHL in GAA and fifth in save percentage. He has started the past 14 games for the Blackhawks. He missed six games because of a lower-body injury in October.

Antti Raanta will replace Crawford as the starting goaltender against the St. Louis Blues on Wednesday. Raanta is 1-2-0 with a 2.03 GAA and .933 save percentage this season. He last played for the Blackhawks on Oct. 25.

Scott Darling will back up Raanta. Darling was recalled from the AHL on Wednesday and is 2-1-0 with a 1.98 GAA and .933 save percentage for the Blackhawks this season.

"I thought the team's played well; he's a big part of the success we had on [our recent road] trip," Blackhawks coach Joel Quenneville said of Crawford. "He's been rock solid every game. Our goaltending each and every night this year has been really good, gives a chance to win every night. I have to commend all of our goalies.

"When [Crawford] went down last time, both goalies came in and did a great job for us. We're going to need them right now."
