Harry Zolnierczyk knee on Mathieu Perreault

From the replay, it does look like the Flyers forward Harry Zolnierczyk catches Capitals forward Mathieu Perreault with a "dirty" knee check, just like Taylor Hall hit Cal Clutterbuck. It's a bit of a different angle so it's not as cut an dry in my opinion. If I was a betting man, and I am, I think a suspension is coming for Zolnierczyk

I would imagine that The NHL's Department of Player Safety will take a look at this hit. It's an unnecessary hit at the end of the game.
