Not NHL, but nice story nonetheless. A Bantam tournament in NS over the weekend, on team had some people and the weather stopped some others from attending. In total they were down 9 skaters and lost 5 - 0.
I think anywhere from 5-10 is reasonable, given that I don't think Kassian made a conscious decision to try to stab someone with his foot, and factoring in that he's already been suspended this season. I'd be pretty surprised if it's not in that range.
