In return, the Blackhawks have acquired two youngsters in the 24-year-old Murphy and 22-year-old Dauphin who have little track record in the league.

“Niklas’ contributions to the three Stanley Cup championship teams are well known but his dependability as a teammate, selfless attitude and the way he represented the Chicago Blackhawks on and off the ice are what made him such a beloved member of the organization,” Blackhawks general manager Stan Bowman said in a statement. “He made his debut in Chicago in 2008 and quietly established himself as one of the toughest competitors in franchise history. We wish he and his family continued success.”
