The Four Nations Face-off's marquee matchup took an ugly turn before the puck even dropped. Ahead of the long-awaited game between Team USA and Team Canada, fans booed the U.S. national anthem, continuing a recent trend of Canadians expressing their displeasure with the Americans.

As the “The Star-Spangled Banner” played, many in the Bell Centre crowd booed loudly, despite a pre-anthem plea to show respect.
