CHICAGO – A terrific start gave way to a scary scene Tuesday for Blackhawks forward Marian Hossa.

Early in the third period, Vancouver Canucks forward Jannik Hansen elbowed Hossa in the back of the head as the Hawks’ winger tried to handle the puck. Hossa remained on the ice for a couple of minutes before getting up slowly and walking to the locker room.

The sequence would have been troubling for any Hawks player, but especially so for Hossa, who left the ice on a stretcher last season after a blind-side hit by Phoenix Coyotes forward Raffi Torres. Hossa sustained a concussion on that play and required months to recover.
