Former Manchester United defender Marcos Rojo was involved in an amazing post-match brawl after his Boca Juniors were beaten by Atletico Mineiro in the Copa Libertadores.
Boca were left incensed after a goal from Marcelo Weigandt was controversially ruled out by VAR in the second-leg of their round of 16 tie against Brazilian side Atletico Mineiro.
The match went to penalties where Boca were defeated 3-1 and the evening soon descended into chaos as the Argentine side tried to break into the Mineiro dressing room before later clashing with police, who were forced to use tear gas in response.
La Nacion reports events took a turn for the worse when Sergio Coelho, President of Atletico Mineiro, provoked the Boca players from the doorway of their dressing room.
This lead to an initial reaction from Boca's Raúl Cascini and players were seen on video shoving each other and throwing items.
Police attempted to intervene in a bid to diffuse the escalating violence and they used tear gas canisters in their effort to do so.
Boca legend Juan Roman Riquelme, the club's vice-president, later said: "When they were in the dressing room, you see a person in a suit who pushed the boys and insults them. The policemen threw gas in the players' faces.
"They gas, what do you do? Do you defend yourself or do you let them hit you? You see the president throwing bottles, the police... they don't say anything to them. That's the truth."
