Henrik Karlsson will dress as Chicago's backup goalie when the playoffs begin Tuesday night.
He will occupy the bench, with Corey Crawford in goal, because Ray Emery isn't ready to return from his lower-body injury in Game 1 against Minnesota.

Chicago has called up Henrik Karlsson.
Karlsson has a 2.86 GAA and .898 save percentage in 18 games with AHL Rockford this season. Carter Hutton might start on Saturday so that Corey Crawford can get a game off. If that happens then there's a chance that Karlsson will serve as the backup so that Crawford can take the day off entirely.

Henrik Karlsson has been called up by the Chicago Blackhawks.
Corey Crawford might be suffering from an injury as he wasn't part of Chicago's morning skate. Either way look for Karlsson to be the backup goaltender on Friday.

One reason Henrik Karlsson was dealt to Chicago was to open up a roster spot.
The NHL allows each team to have only 50 players under contract and while the Flames were at 49 before the trade, they figure on signing American World Junior Championship star Johnny Gaudreau to a deal after the college hockey season ends. Karlsson also lost his backup spot to Leland Irving which was the real reason.

The Calgary Flames have traded Henrik Karlsson to Chicago for a seventh round pick in the 2013 Draft.
Karlsson lost his job as the backup to Miikka Kiprusoff in Calgary as Leland Irving will now have the honors. The Blackhawks sent Karlsson to the AHL Rockford IceHogs where he will provide insurance to Corey Crawford and Ray Emery. The draft pick was originally the Ottawa Senators which the Blackhawks acquired in an earlier deal.

Henrik Karlsson has been assigned to the minors.
Karlsson lost the backup job to Leland Irving following the Flames' abbreviated training camp.

Henrik Karlsson has been placed on waivers by the Calgary Flames.
What makes this weird is that Leland Irving was also waived by Calgary. It's not clear what there plans are given that they've exposed both of their potential backup goaltenders.
