An American university ice-hockey advised their fans to not wear clothing or props containing “Irish symbolism” while travelling around Belfast as it may be “deemed offensive” before deleting the tweet following an online backlash.

Notre Dame Hockey, whose team is called Notre Dame Fighting Irish men’s ice hockey team, is the college team of the University of Notre Dame.

They are set to play alongside the Belfast Giants as part of the Friendship Four 2024 tournament from the 29 to 30 November.

In the now-deleted social media post, the hockey team asked fans to avoid wearing green, anything with the terms “fighting Irish” or “Irish” or anything which may features shamrocks, leprechauns or the Ireland flag.

“We can’t wait to see your Notre Dame in Belfast gear inside SSE Arena,” the team posted.

“Just a reminder to avoid our Irish symbolism, that may be deemed offensive to some, while out around town.”

They also advised fans they can wear the team’s colours – navy and gold, or anything with their logo while around the city.

The post was deemed “embarrassing” by some in the replies, with one fan writing: “My kids have travelled all over Ireland in all the gear you say not to wear and received nothing but love. As a Notre Dame graduate married to an Irish woman this is embarrassing and you should take down the post immediately.”

Another said: “This tweet is more offensive than any American university t-shirt abroad ever would be. If the fans of the Fighting Irish should be made to feel embarrassed of their programme, then don’t schedule the trip” while another replied: “This tweet far more offensive than anything that an actual fan might do with a shirt or whatever.”

The University of Notre Dame du Lac is a private Catholic research university in Notre Dame, Indiana in the United States and one of the oldest university’s in the state.

All of the school’s athletic teams are referred to as the ‘Fighting Irish’ with the mascot being a leprechaun.

Earlier this month the team released a special ice hockey jersey for the upcoming tournament at the SSE Arena at the end of the month with the letters and numbers on the jerseys are detailed to look like those in the Book of Kells with the Celtic knot running through them, along with a new logo for the team specifically for the tournament.
