Minnesota Wild captain Mikko Koivu was placed on injured reserve Monday after undergoing surgery to repair a broken ankle, adding to the Wild's injury woes.

Koivu suffered an ankle fracture in the Wild's 5-3 win over the Capitals on Saturday night, a game in which Koivu had two assists. He is expected to be back in the lineup in about four weeks, or right about the time the Olympic break hits.
