Here's the actual rule
Rule 59 – Cross-checking
59.1 Cross-checking - The action of using the shaft of the stick between the two hands to forcefully check an opponent.
59.2 Minor Penalty - A minor penalty, at the discretion of the Referee based on the severity of the contact, shall be imposed on a player who “cross checks” an opponent.
59.3 Major Penalty - A major penalty, at the discretion of the Referee based on the severity of the contact, shall be imposed on a player who “cross checks” an opponent (see 59.5).
The ref saw a cross check that resulted in a knocked out player. It doesn't say you have to cross check someone in the head I mean Jamie Benn got a major for this
For me it wasn't a major, but I can see why the refs called it. All I said was it's not an unreasonable call based on what happened in real time. Ref sees Eakins stride at a guy, cross check him and send him over where he hits his head on the ice and is knocked unconscious.
