The Chicago Tribune is reporting that goaltender Corey Crawford is not with the team for the morning skate. The Blackhawks, the only team in the League without a regulation loss, host the San Jose Sharks on Friday (8:30 p.m. ET, NHLN-US).
Karlsson, 29, is 2-2-0 with a 2.33 goals-against average and .919 save percentage in four AHL games the Rockford IceHogs.
Karlsson was acquired by the Blackhawks from the Calgary Flames last month for a 2013 seventh-round draft pick.
If you want to prove people wrong, you've just got to go out and do it. Yeah, we blew 3-2 series leads the last two years, but no one is going remember that if we go out there on Saturday night and beat these guys and go play in the Stanley Cup Final. We need to get back to work and we'll start to do that tomorrow.
