There are specific reasons as to why a major penalty i called during a game. A major penalty is committed if:
- a minor penalty is done in an intentional and aggressive manner
- a player engages in rough play
- a boarding, body contact, charging, cross checking, or elbowing that includes initial contact to the head or contact from behind- if the on-ice official sees the contact as any intent to injure a match penalty is to be assessed
All major penalties are four minutes fully served and if combined with a minor penalty the major penalty is to be served first with the minor penalty following.
