Hjalmarsson has been suspended for the remainder of the preseason and Opening Night, the NHL Department of Player Safety announced Monday.

EDGE Analysis

The league determined Hjalmarsson elevated into the head of Blues forward Ty Rattie and issued a suspension for charging. Without the 29-year-old the Hawks are suddenly thin at the blueline with Duncan Keith (knee) still recovering. Michal Rozsival will likely slot into the lineup during Hjalmarsson's ban.
