It turns out that general manager Ken Holland's initial guess as to how long backup goaltender Jonas Gustavsson will be out was a little too optimistic.

After news broke Thursday that Gustavsson had dislocated his shoulder, Holland suggested that Gustavsson would miss a few weeks. At the time, the team wasn't sure if he would need surgery to repair the shoulder.

Holland updated the Swedish goalkeeper's status Friday, saying that Gustavsson will avoid surgery but is going to miss approximately two months.

Gustavsson's absence will test the Red Wings' goaltending depth behind Jimmy Howard, who hasn't yet proven he can handle a substantial load in the crease. Howard appeared in 63 games in 2009-10 and 2010-11, but played just 93 games total over the past two years. In the season's early going, he's played 10 games, posting a robust .928 save percentage.

Once thought to be disappointment, Gustavsson has developed into a solid backup. In 37 games as a Red Wing, the 30-year-old has a .908 save percentage and 2.30 goals-against average.

The Red Wings have called up Petr Mrazek to handle backup duties while Gustavsson's out. Mrazek has appeared in 11 games for Detroit over the past two seasons, posting a .926 save percentage. He has a 3.80 GAA in four games with Grand Rapids of the American Hockey League this season.
