St. Louis Blues forward Alexander Steen had successful surgery on his left shoulder and will be re-evaluated in 16 weeks, the team announced Friday.
That time frame would likely prevent Steen from playing in the World Cup of Hockey, scheduled for Sept. 17-Oct. 1. Steen was among the first group of 16 players selected to Team Sweden's roster in March.
Steen dislocated the shoulder when he crashed into the boards during a game against the Arizona Coyotes on Feb. 20. He missed 15 games but returned for the final six games of the regular season and took part in all 20 of the Blues' games during the Stanley Cup Playoffs.
Steen, 32, had 17 goals and 52 points for St. Louis during the regular season. He set career highs with four goals and 10 points in 20 playoff games. The Blues defeated the Chicago Blackhawks and Dallas Stars before they were eliminated in six games by the San Jose Sharks in the Western Conference Final.
In 11 NHL seasons with the Blues and Toronto Maple Leafs, Steen has 197 goals and 481 points in 746 games.
