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.
There's no discouragement in that room. There's no issues there at all to be honest with you. It's more about, 'Hey, it's opportunities for players.' And if we become that bad of a team because of one player, it's not a real good sign for our hockey club. So this is part of sports. It's part of hockey.
