Straight from the DoPS:
Boston’s Brad Marchand will have a hearing tomorrow morning for spearing Tampa Bay’s Jake Dotchin.— NHL Player Safety (@NHLPlayerSafety) April 5, 2017
The league tends to specify if a hearing is in person, so assume this is by phone.
In any case, it's clear that Brad Marchand will be seeing some kind of punishment.
It's almost too easy for the league to give him two games. It won't cost the Bruins a playoff spot, it won't take a star out of a playoff game and it will look like the league stood firm.
We'll know more tomorrow.
