Darwin Nunez faces a ban as CONMEBOL open investigation after Liverpool star is seen throwing punches in brawl with Colombia fans after Uruguay crash out of Copa America

After 10-man Colombia beat Uruguay 1-0 in a Copa America semi-final, tempers flared. Guillermo Varela was sent off, and a number of players then headed into the stands to berate Colombian fans. In a mass brawl, Nunez appeared to be punched by a fan, and in retaliation, he was seen throwing punches back.

Now, CONMEBOL has opened an investigation into the violent scenes. Objects were thrown and some supporters were visibly injured. Uruguay captain Jose Maria Gimenez claimed that there was almost a "disaster" in the stadium, as he joined Nunez in jumping into the stands.

In a statement, CONMEBOL said: "The Disciplinary committee of CONMEBOL has opened an investigation to understand the sequence of events and the responsibilities of those involved in the acts of violence that occurred at the end of the match between the national teams of Uruguay and Colombia.

"On the eve of the final of Copa America, we want to reaffirm and warn that no action will be tolerated that tarnishes this global football celebration, which involves both the players and the fans present in the stadium, and which will be watched by hundreds of millions of viewers worldwide.

"It is unacceptable that an incident like this turns passion into violence. Therefore, no behaviour that harms the sporting competition and the most beautiful spectacle in the world, which belongs to the entire football family, will be tolerated."

Uruguay may not be able to win the Copa America but they have one more game to play. They will face Canada in the third-place play-off this weekend.
