Watch: Chilean anthem played for Uruguay at Copa America Centenario

Copa America Centenario organisers issued a formal apology Sunday after game operations at University of Phoenix Stadium in Arizona mistakenly played the Chilean national anthem for Uruguay's national team.

This evening during the pre-match ceremony, due to human error, we inadvertently played the incorrect National Anthem. We sincerely apologize to the Uruguayan Federation, the Uruguay National Team, the people of Uruguay and to the fans for this mistake. We will work with all parties involved to ensure such an error does not occur again.

There were confused, perhaps some exasperated looks in the Uruguayan lineup, but the team and its fans handled the situation well. It even appeared as though team captain Diego Godin was singing the lyrics for the correct anthem.

The error adds to what's been an inauspicious start to the tournament. There have been attendance issues in certain stadiums across the United States, and, frankly, the overall quality of play won't help shroud this sort of blunder.
