Fans of Dock Sud, who were losing 1-0 to Deportivo Laferrere in the Primera C (fourth tier) championship, rioted near the end of their match setting cars alight and fighting with police, who responded with rubber bullets and tear gas.
The referee abandoned the match, the second such decision in four days after Friday's rioting by fans of San Carlos, who were losing 2-0 at home to Boca Unidos and doomed to relegation from the second tier Primera B Nacional.
The Argentine Football Association is expected to uphold the result of the match at San Carlos which would seal their relegation.
