Milan Lucic has some explaining to do.
The Los Angeles Kings forward has a hearing Sunday with the NHL's Department of Player Safety for landing a punch to the head of Arizona Coyotes defenseman Kevin Connauton on Saturday night.
Lucic was thrown out after retaliating against Connauton, who slashed him in the third period of Arizona's 3-2 victory.
The Kings winger was critical of referee Brad Meier after the game.
Lucic was suspended for a game in 2009, and for another in 2011.
