Vancouver Canucks forward Jannik Hansen has been suspended one game for a hit to the head on Chicago Blackhawks forward Marian Hossa.
Hansen struck Hossa in the back of the head with his forearm during the third period of the Blackhawks' 4-3 win Tuesday.
Hossa was reaching for a puck in the air as Hansen, who had also reached for the puck, closed his glove and delivered the hit.
The injury knocked Hossa out of the game after he had already scored two goals. There is still no timeline for his return.
Hansen, who was assessed a minor penalty for roughing after the hit, will forfeit $7,297.30 US and will miss the Canucks' game in Dallas on Thursday. Hansen has three goals and four assists in 15 games.
The Blackhawks will be left to hope Hossa, who has eight goals and six assists in 16 games this season, isn't gone for long after suffering his second head injury in less than a year.
Hossa was knocked out of the playoffs with a concussion in April 2011 after a hit from behind from Phoenix forward Raffi Torres.
Torres was suspended 25 games for the incident, although that penalty was later changed to 21 games.
