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 don't think today was my most solid game that I've had, some rebounds here and there. I know there's a lot of work to do, not every game is going to go as good as these last few. I've just got to make sure I keep working and keep trying to get better.
