(CHICAGO) – The Chicago Blackhawks made another trade for a veteran defenseman on Monday, acquiring Calvin deHaan in a deal with the Carolina Hurricanes. The Blackhawks also received minor league forward Aleksi Saarela in exchange for defenseman Gustav Forsling and goaltender Anton Forsberg. Chicago has been looking to upgrade its blue line since it missed the playoffs last season for the second straight year. It acquired Olli Maatta in a trade with Pittsburgh on June 15. The addition of de Haan and Maatta raises questions about what the Blackhawks might do with the rest of their defensemen. They also have Duncan Keith, Brent Seabrook, Connor Murphy, Erik Gustafsson, Carl Dahlstrom and Slater Koekkoek on their roster. The Hurricanes' acquisition of Forsberg comes with the two goalies who helped lead them to the Eastern Conference final: veterans Petr Mrazek and Curtis MeElhinney, eligible for free agency on July 1. DeHaan was selected by the New York Islanders with the 12th overall pick in the 2009 draft. He spent his first six seasons with the team before joining Carolina last summer, signing a four-year contract worth $18.2 million. The 28 year old de Haan had one goal and 13 assists in 74 games last season. He also had a goal in 12 playoff appearances.
