Unlike Europe, the United States (and Canada) always plays the national anthem before every game, from American football to MLS. All games, internal or international, must be postponed until Francis Scott Key's hymn is sung. During NFL games, this occurs just prior to the start of the opening kickoff. The National Anthem is also played prior to any NCAA basketball game during time out, as well as before any baseball game when the national anthems of both teams are being played. In addition, coaches in the NFL and college sports ask their players to stand for the national anthem. If anyone refuses, then that person will not play in that game. The only major North American sport that does not have the national anthem performed before each game is Canadian ice hockey. Instead, the "Ode to Joy" by Ludwig van Beethoven is played before all NHL games. Other than at American football games, the song is never sung. Instead, fans either stand or place their hands over their hearts while the national anthem is played on television. This custom arose after former San Francisco quarterback Colin Kaepernick decided to protest racial injustice by refusing to stand for the national anthem. His action sparked other athletes to follow his lead.
