ATLANTA -- In their own apparent protest, Atlanta Thrashers fans made their own voices heard Friday night.

The Atlanta Journal-Constitution reported Saturday that fans booed during the Canadian national anthem before the Thrashers' NHL game against the Ottawa Senators.

It might have been a response to events from Thursday night, when Montreal fans booed during the U.S. national anthem before the Canadiens' game against the New York Islanders.

Canadiens president Pierre Boivin issued an apology Friday. The Thrashers organization did the same that night.

"The entire Thrashers' organization regrets the actions of a small number of fans that behaved disrespectfully during the Canadian anthem tonight prior to the Thrashers' game against the Ottawa Senators," the statement read as printed in the newspaper.

"The Thrashers' organization firmly believes this type of behavior has no place in professional sports. We hope that this was an isolated incident and apologize to anyone who was offended, including the Canadian-born members of both teams."
