Hagelin suffered a shoulder injury on Tuesday.
The coach of Sweden's team said of losing Hagelin, " It's boring. It would have been fun to see him debut."
The coach added, "It's a player who has developed all his hockey not just skating all highlights. I see him as a complete player"
A report from Mikael Widerberg says that Hagelin suffered the shoulder injury over a week ago when he was "tackled" in a game against Djurgården. He notes that Hagelin played on but suffered another "bang" to his shoulder that caused him to leave the game on Tuesday.
Hagelin missed SSK's game last night.
Hagelin, along with prospects Jesper Fasth and Oscar Lindberg, were named to the international tournament.
