Nolan Patrick took a nasty hit to the head

Yesterday, the Avalanche won 2-0 against the Golden Knights. It was a well anticipated game, and there really was a playoff atmosphere between those two teams.

However, the game finished earlier for Nolan Patrick after he took a hit to the head by Avalanche forward Nathan MacKinnon.

The former Flyers player didn't continue the contest, and could miss some time. He has a concussion/migraine history so it's a bit scary. This year, Patrick played 18 games and registered 6 points.

According to you, is this hit nasty or not?
