The CONCACAF Nations League final between the United States and Mexico was marred by unruly fan behavior that included objects thrown on the field and a brief pause in the game due to fans using an anti-gay chant.

The pause occurred during the final moments of the second half before the game went to extra time in the U.S. men's national team's 3-2 win over Mexico. Play resumed after three minutes as players on both sides pleaded with the crowd to stop using the chant.

After Christian Pulisic netted the would-be game winner off a penalty and ran to the corner to celebrate with the rest of his teammates, Giovanni Reyna was hit in the face with an object as fans in the stands threw items such as cups onto the field.

Reyna, who scored the USMNT's first goal in the first half, lay on the ground for several minutes before walking off the field with trainers.

As the game neared its conclusion, a fan ran onto the field before being tackled and escorted off the field by security personnel.

This was the second tournament match to be halted due to anti-gay chants at Denver's Empower Field at Mile High. Mexico's semifinal win over Costa Rica was also briefly paused. That match also saw several fans ejected from the stadium.

Mexico has struggled throughout the years with stopping supporters from making anti-gay chants. In March, FIFA opened an investigation into anti-gay chanting by Mexico supporters during an Olympic qualifier against the Dominican Republic.
