Canadian fans booed the American national anthem when the teams met in a round-robin match in Montreal, which was followed by three fights in the first nine seconds of the game.

The result was the culmination of a midseason tournament that featured stars from Canada, Finland, Sweden and the United States — and a surprisingly political atmosphere.

Team USA will play its biggest game in 15 years on Thursday night when it meets Canada in the 4 Nations Face-Off championship. The Americans have already shown they can beat their bitter rivals, but the Canadians will do everything they can to avenge Saturday's loss and win the tournament.
