Following the final whistle of the Copa America semi-final, the striker was observed physically addressing Colombian supporters in the stands.
El País, a news agency, claims that chaos started near the locations of the Uruguay team’s friends and relatives.
Núñez has not yet made any public remarks about the event.
Images of Nez scaling barriers and entering the packed Bank of America Stadium in Charlotte, North Carolina, were obtained by TV cameras and spectators.
Then, while others attempted to hold him, he was spotted confronting Colombian supporters.
According to reports, the incident implicated other Uruguayan players.
According to Reuters, Uruguay captain José María Giménez described the situation in the crowd as a “disaster” and stated that the players were attempting to safeguard their families.
He went on, “We had to protect our families because there were no police.” This is the result of two or three inebriated individuals who lack drinking experience.”
After the altercation, Núñez was spotted comforting his kid on the pitch.
Conmebol, the authority that oversees football in South America, “strongly condemned” the event and announced that an investigation would be conducted.
“There is no place for intolerance and violence on and off the field,” it continued.
The fight broke out after Uruguay lost their final four matches 1-0 to Colombia, eliminating them from contention.
