Flyers winger Wayne Simmonds was the subject of racial slurs after getting in a fight during a game in the Czech Republic on Sunday, Yahoo! Sports reported.
Fans chanted "opice," which means monkey, according to reports.
The marketing director of Chomutov, which faced Simmonds' team, issued an apology.
"We are disgusted with the behaviour of small groups of spectators who significantly damaged the reputation of the whole. ... club. We would like to deeply apologize to Mr. Simmonds and the Liberec players," David Dinda said in a statement.
Last year, during an exhibition game in London, Ont., a fan threw a banana at Simmonds as he went in on a breakaway during a shootout.
Simmonds had a career-high 28 goals last season.
