With Mikko Koivu sidelined, the Wild could be in big trouble.

Koivu, Minnesota's do-everything center who last week was named to the all-star team, likely will not be back before the NHL All-Star Game on Jan. 29 because of an upper-body injury, according to coach Mike Yeo.

It's a major loss: Koivu missed four games earlier this season because of a groin injury, and the Wild lost them all.

He missed 11 games late in the 2010-11 season with a broken finger, and the Wild lost seven of those, two by shootout.
