With El Tri holding a one-goal lead and a one-man advantage in the second half of the tournament opener for both sides, the match took a turn for the worst when the sending off of Mexico midfielder Andres Guardado and an equalizer from Uruguay's Diego Godin sparked outrage among Mexican fans.

With bottles being tossed on the pitch as the Uruguay players celebrated, fights also broke out in the stands. Footage from inside the University of Phoenix Stadium shows fans fighting along the stairway just a few rows away from the playing field.

The Mexican team recovered with two goals late on to take over the match and claim all three points.

Before the match even began there was already controversy when Copa America organizers at the stadium played the wrong national anthem for Uruguay, with the Chile anthem being played instead in an incident the tournament said was caused by "human error."

"This evening during the pre-match ceremony, due to human error, we inadvertently played the incorrect national anthem," read the statement. "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."
