According to Arizona Coyotes Insider Craig Morgan, another member of the recent Blackhawks Cup winning teams is retiring from the NHL: Niklas Hjalmarsson. Unlike Brent Seabrook earlier this season, Hjalmarsson is not expected to formally announce his plans to stop playing hockey in the NHL.
Per source, Coyotes UFA D Niklas Hjalmarsson is retiring. I don't expect a formal announcement or statement from Nik. Those who have covered him or known him know that is not his style.
He was an integral part of 3 Stanley Cups in Chicago and the consummate pro on/off the ice.
