According to Aftonbladet (relayed by HockeyNews.se), Carl Dahlström will indeed make use of that clause. Supposedly, the defenseman is set to play in the National League next season.
The SC Rapperswil-Jona Lakers are supposedly one of the options Dahlström has. The defender has appeared in 50 regular-season games for Färjestad this season, recording one goal and 14 assists.
