Danubio leap-frogged Nacional to go top of the championship's first stage after their 1-0 win but the match was overshadowed when fans fought on the field. Shortly after the final whistle, dozens of visiting Nacional fans found their way through a hole in the fencing, invaded the pitch and managed to grab a Danubio flag. This enraged the home supporters who also ran onto the field and a pitched battle ensued in which fans, some armed with iron bars, punched and aimed karate kicks at each other. Media said that police took around 15 minutes to bring the situation under control.
