How many games will Brad Marchand get?

Brad Marchand was a bad boy last night, taking a page out of P.K. Subban's book and slewfooting the heck out of Derick Brassard:

Ouch. No wonder everyone hates the Little Ball of Hate.

Anyhow, we all know that Brad Marchand generally gets negative benefit of the doubt. As someone put it, "the doubt of the benefit." And, per Amalie Benjamin, the league is looking at it:

The Department of Player Safety will be reviewing the Brad Marchand slew foot, per a source.

So, what do y'all think?

• He's been suspended before.
• There was no injury on the play.
• There was no penalty called on the ice.
• Everyone's been talking about it in the hockey media.

Does Brad Marchand get supplemental discipline for this slewfoot?
