David Backes got tossed from the game for this headbutt

As written about earlier in the night, Brad Marchand hit John Tavares with his hands to the face, receiving a five minute major for interference, meaning one Bruin was already in trouble.

Later in that period, David Backes got into it with Andrew Ladd and subsequently got tossed from the game.

The infraction:

Huh. That wasn't much of a headbutt.

Thoughts? Seems like the officials were "major happy" tonight.
