The Minnesota Wild will be without captain Mikko Koivu for the next month.

The Wild placed Koivu and goalie Josh Harding on injured reserve Monday, when their first-line center and leading scorer with 35 points in 44 games underwent surgery to repair a broken ankle. Koivu was hit by a puck Saturday against Washington. The Wild said the operation went as planned and Koivu was expected to be fully recovered and playing again in approximately four weeks.

Koivu has eight goals and 27 assists. He's third among NHL forwards in time on ice with an average of 21 minutes and 34 seconds per game.

The Wild play at Los Angeles Tuesday, and left wing Zach Parise and defenseman Jared Spurgeon are already on injured reserve with foot injuries. Harding has missed the last two games due to an unspecified illness; he's been adjusting to new medication for multiple sclerosis. Harding leads the league with a 1.65 goals against average.

Defenseman Jonathon Blum and forward Erik Haula were recalled from AHL affiliate Iowa Monday to fill out the roster.
