Dumba was called for a roughing penalty, drawn by Pavelski, according to the league’s official report. From Rule 51:
Roughing is a punching or slamming motion with or without the glove on the hand, normally directed at the head or face of an opponent … A minor penalty shall be imposed on a player who strikes an opponent with his hand or fist.
Clearly, there was no roughing against Pavelski on the play. Dumba did exchange gloved punches with the Stars’ Max Domi, who also received a matching roughing penalty, along with a ten-minute misconduct penalty. We’ll chalk this up to an accounting error. Roughing penalties to both Dumba and Domi seem appropriate here.
