NHL player safety makes official decision on Brad Marchand suspension

40.1 Game Misconduct – Any player who deliberately applies physical force in any manner against an official, in any manner attempts to injure an official, physically demeans, or deliberately applies physical force to an official solely for the purpose of getting free of such an official during or immediately following an altercation shall receive a game misconduct penalty.

40.4 Automatic Suspension – Category III – Any player who, by his actions, physically demeans an official or physically threatens an official by (but not limited to) throwing a stick or any other piece of equipment or object at or in the general direction of an official, shooting the puck at or in the general direction of an official, spitting at or in the general direction of an official, or who deliberately applies physical force to an official solely for the purpose of getting free of such an official during or immediately following an altercation shall be suspended for not less than three (3) games.

It's officially after 5 pm and it's clear the NHL won't be issuing any supplemental discipline for his shove on the linesman. This is a clear violation of rule 40.1, but the league has decided to ignore it.
