Late in the first period of Sunday's Washington vs. Chicago game, Alex Ovechkin and Brian Campbell were involved in a race for a loose puck, and just after Campbell played the puck, Ovechkin gave him a shove from behind, sending him crashing into the boards.
Ovechkin was issued a five-minute major and a game misconduct (his league-leading third of the season) for boarding.
According to NHL rule 42.3, the referee "may assess a major penalty, based on the degree of violence of the impact with the boards, to a player or goalkeeper guilty of boarding an opponent." Once the major penalty is issued and the player on the receiving end of the hit is injured -- as Campbell was -- a game misconduct is automatic (rule 42.5).
This hit comes just a week after Montreal's Maxim Lapierre was suspended four games for boarding San Jose's Scott Nichol on a hit that was, admittedly, much later than Ovechkin's hit on Campbell. There was no penalty called on that play.
Ovechkin has already been suspended once this season, receiving a two-game banishment for a knee-to-knee hit on Carolina's Tim Gleason, and he's all but guaranteed to see another one. This is the second time this season Ovechkin has been issued a game-misconduct for boarding an opponent, and according to rule 42.6: Any player or goalkeeper who incurs a total of two (2) game misconducts under Rule 42 and/or Rule 44, in either Regular season or Play-offs, shall be suspended automatically for the next game of his team. For each subsequent game misconduct penalty the automatic suspension shall be increased by one game.
UPDATE: Apparently, since it's been more than 41 games since his last game misconduct for boarding, Ovechkin will not be subjected to the automatic one-game suspension. That doesn't mean he still can't be suspended.
UPDATE II: Campbell could be done for the season.
