According to this site (and several others), Lucic's penalty against Maxim Lapierre at the end of Game 2 vs. the Canadiens was changed from a game misconduct to a match penalty, which triggers an automatic suspension until the commissioner rules on the action.

From my viewpoint, certainly not the best of outcomes for the Bruins.  After the Habs got away suspension-free for their Game 1 cheap shots (Lapierre going after Kessel after a goal, Kostopoulos swinging an elbow at Hunwick in the closing seconds), there seems to be some injustice to it all, but it's the rule.  I'm sorry that we'll miss his physical presence if he is indeed suspended, but we still have guys like Stuart and Kobasew who are really stepping up the gritty play this series.
