Santiago Wanderers and Colo-Colo fans clashed at the Elias Figueroa Brander Stadium before their Chilean Primera Division match on Sunday.
Just before kick-off, fans from both sides invaded the pitch and started fighting. They were hitting each other with belts, metal bars and anything they could get their hands on.
The players were taken off the pitch and the match was abandoned.
Earlier that day, rival Santiago Wanderers and Colo-Colo fans had clashed on the streets of Valparaiso.
