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.
Obviously there's a lot of expectations around me but it's something I try not to focus on. I'm just trying to go out there, be myself on the ice every day, try to get better, be myself around the guys in the locker room. I think that's what's made me successful and the person that I am.
