Watch Nicklas Backstrom's questionable hit on Dan Boyle, which led to Rangers loss

In the final seconds of Game 1, in the midst of a tie game between the New York Rangers and Washington Capitals, Nicklas Backstrom bumped Dan Boyle off the puck in the corner with a big hit.

OK, "bumped him off the puck" is perhaps putting it lightly. He delivered a highly questionable hit to bump Boyle off the puck. It then came free and out to Alex Ovechkin, who dumped it to Joel Ward in front. Ward buried the game-winning goal at the buzzer.

Here's the hit.

There's definite contact to the head here. It also looks like it comes from behind.

What do you think? Is this suspension worthy? Will the NHL call Backstrom in for a chat with the Department of Player Safety?
