Toronto Maple Leafs goaltender Frederik Andersen will be sidelined three-to-four weeks after sustaining an upper body injury at a pre-Olympic qualifying game Friday, general manager Lou Lamoriello announced.

Andersen is expected to be back for the start of the regular season, but will miss the World Cup of Hockey, where he was selected as one of three goalies to Team Europe.

After learning of the injury, the Leafs flew Andersen from Belarus to Toronto over the weekend for an evaluation with team doctors.

The Maple Leafs acquired Andersen from the Anaheim Ducks via trade during the offseason, after a season in which the 26-year-old went 22-9-4 with a 2.30 goals against average and .919 save percentage.

There is no word yet on who may replace Andersen on Europe's roster.
