Children fled for safety as horrific rioting erupted when Brazilian side Cruzeiro were relegated for the first time in their 98-year history.
Riot cops deployed tear gas and fans fought with police as those in the stands ripped seats out and threw them at players.
The referee abandoned Cruzeiro's clash against Palmeiras with five minutes to go shortly after the visitors' second goal at the Mineirao Stadium in Belo Horizonte.
Some fans had already evacuated the ground as ugly skirmishes and fireworks broke out in the terraces.
But shocking video footage showed a one man carrying what appeared to be his son to safety while others fiercely protected the most vulnerable from the violence.
Others were carried out on bloody stretchers with clashes taking place on the street outside the stadium too.
One journalist there said: "The environment outside of Mineirao is a war zone.
"Even some broadcast booths have seen projectiles fly by them."
Cruzerio actually started the season well, winning the Mineiro state championship.
But the club was rocked in May by a corruption scandal and the knock on effect was huge, with the side hiring and firing four managers over the course of the season.
