Andrew Shaw learned on Tuesday what's not acceptable when it comes to hitting goaltenders.
The Blackhawks forward was suspended three games for charging Coyotes goalie Mike Smith during the teams' Game 2 clash on Saturday.
Shaw was assessed a major penalty for charging and received a game misconduct following the second-period hit. League disciplinarian Brendan Shanahan decided that wasn't enough, though, and issued the supplemental discipline.
Check out the video below to hear Shanahan's assessment of the hit and the subsequent suspension.
