Gustafsson was 2-0 with a 1.99 goals against average in three games this season for the Iowa Wild. The sixth-round pick in the 2010 draft played in his native Sweden last season and has not appeared in an NHL game. He'll be the backup to Niklas Backstrom when the Wild play at Chicago Saturday.
Coach Mike Yeo said after practice Friday that Harding was feeling better but won't travel to the game.
Backstrom's relief appearance for Harding Thursday in the win over Carolina was his first action since he suffered a lower-body injury Oct. 8.
I remember the first time at Wrigley Field all of us had the long johns, the turtlenecks and the extra equipment because we were afraid of being cold. Halfway through the first period everybody's ripping everything off and we just ended up wearing what we would normally wear for a game at the United Center.
