Should they penalise and suspend this hit? If they cared about the health of players, they would. If they base it one precedent, then it's probably just a penalty.
I don't like some of the comments here that seem to suggest that a taller player hitting a player in the head is seemingly fine. The responsibility to hit legally should always been on the person throwing the hit. If you're tall, well you need to get lower to throw the hit.
Zadorov had the opportunity to hit through the body, instead he skates and clips Barabanov. Look at their comparative skate positions leading up to and at the point of contact, Zadorov is not going through the body.
