A match in Argentina between Estudiantes and Banfield had to be suspended in the 13th minute after Estudiantes's home supporters threw two flares onto the pitch which promptly exploded, causing acoustic trauma to their own keeper. The first flare came at about the 6th minute, and the opposing team scored 3 minutes later. The referee called off the match when the keeper said he could not continue playing and the chief of the police contingent said that the crowd could cause more trouble.
Just as ugly, some fans began climbing fences after the second explosion, and were confronted by angry Estudiantes captain Juan Sebastian Veron, who shouted at them, "Get down... get down or I'll beat you up."
This type of hooliganism is exactly what MLS and FOs throughout the league fear. While I have yet to see any evidence that this type of behavior would occur here, it's not hard to understand why FOs are so neurotic in stamping out any signs of possible hooliganism. They never want to be in the position of Estudiantes's president, Enrique Lombardi, who said that "it seems this is the price we have to pay."
