Several fans were ejected from Denver's Empower Field at Mile High on Thursday following antigay chanting during Mexico's CONCACAF Nations League semifinal game against Costa Rica.
The match was stopped for three minutes and the fans ejected during stoppage time at the end of a 0-0 tie, which Mexico then won 5-4 in a shootout.
"Due to discriminatory chanting, the referee has stopped the match for up to three minutes," a CONCACAF tweet read. "This action is part of @Concacaf's antidiscrimination protocol."
As reported by ESPN, the Mexico club has struggled throughout the year to deal with stopping supporters from making anti-gay chants. In March, FIFA opened an investigation into anti-gay chanting from Mexico supporters during an Olympic qualifier against the Dominican Republic, before a further probe for a qualifier against the United States.
Last week, Mexican Football Federation president Yon de Luisa said the support of national team players will be crucial to stamping out anti-gay chants during Mexico's games.
Mexico will face the United States in the final Sunday after the USMNT defeated Honduras 1-0.
