(DULUTH NEWS TRIBUNE) — Student season-ticket holders for University of Minnesota Duluth men’s hockey games were warned last week to clean up their acts after complaints to the athletic department about racist chants during UMD’s series against the University of North Dakota Fighting Sioux on Feb. 10-11.

“There were some reports on some chants coming from the student section that certainly would have been considered inappropriate,” Athletic Director Bob Nielson said. “We decided it was an opportunity to reinforce our policy … to focus on cheering for our team and avoid comments that are considered inappropriate.”

Nielson sent the students a letter dated Feb. 17 that warned “any profane, racial, sexist, or abusive comments or actions directed at officials, opposing players or teams will be grounds for removal from the arena” and could result in a forfeiture of season tickets.
