The NHL's Department of Player Safety automatically suspended Dallas Stars forward Mikko Rantanen for one game on Sunday after he was ejected for boarding Calgary Flames forward Matt Coronato.
Under league rules, a player receives a one-game ban after totalling two game misconducts for physical infractions - boarding, charging, checking from behind, clipping, elbowing, head-butting, interference, and kneeing - in fewer than 41 contests.
Rantanen's major penalty and game misconduct in Saturday's shootout loss were his second in only three games.
