WOW: Controversial call against Canada at WJC

Zach Dean, a Golden Knights prospect, was chasing the puck down the Czech's zone when he laid a hit on a Czech defenceman. The referee in charge awarded Dean a game-misconduct after review. The game summary states an illegal hit to the head.

It's no news that the IIHF has really strict standards when it comes to hitting and fighting, but was that overboard? Was this even worth a penalty to begin with?
