According to the whl's discipline page John Stampohar is being suspended 4 games for his open ice interference hit from behind in yesterdays game vs the Oil Kings.
You can watch the hit in one the fight videos I added yesterday down below.
The hit was a dumb decision, the penalty was a little harsh, but justifiable. The guy did back into him, but stampohar just ran him over.
I think if that happened with 2 guys the same size you only see a 2 minute minor penalty. I looked over the last 2 years of suspensions and I couldn't find any previous suspension for Stampohar.
