This hit is shoulder to thing.
The thigh is above the knee in any human I’ve ever seen.
Here’s rule 44:
44.1 Clipping – Clipping is the act of throwing the body, from any direction, across or below the knees of an opponent.
A player may not deliver a check in a “clipping” manner, nor lower his own body position to deliver a check on or below an opponent’s knees.
An illegal “low hit” is a check that is delivered by a player or goalkeeper who may or may not have both skates on the ice, with his sole intent to check the opponent in the area of his knees. A player may not lower his body position to deliver a check to an opponent’s knees.
44.2 Minor Penalty – A player who commits these fouls will be assessed a minor penalty for “clipping.”
44.3 Major Penalty – If an injury occurs as a result of this “clipping” check, the player must be assessed a major penalty (see 44.5).
44.4 Match Penalty – The Referee, at his discretion, may assess a match penalty if, in his judgment, the player attempted to or deliberately injured his opponent by clipping.
44.5 Game Misconduct Penalty – A game misconduct penalty must be assessed anytime a major penalty is applied for injuring an opponent by clipping.
44.6 Fines and Suspensions – There are no specified fines or suspensions for clipping, however, supplementary discipline can be applied by the Commissioner at his discretion (refer to Rule 28).
The officials blew the call.
