Bob Nardella, head coach of the Chicago Wolves in the American Hockey League (AHL), has been suspended 10 games for making homophobic remarks toward an official.

The events took place on Saturday, December 9, against the Stars in Texas. Midway through the third period, Nardella attacked a referee. Officials then charged him with game misconduct.

Player Dominic Franco was also suspended, for a single match in his case.

“The AHL is committed to building a culture that is safe, inclusive and free from abuse, harassment and all forms of immoral behavior,” the league said Tuesday.

Nardella will be able to participate in team activities and practices not taking place on game day. He will be able to return to his team’s bench on January 6.

The Wolves sit in last place in the overall AHL standings, with just 5 wins in 20 games.
