The background is reported to be violent clashes between supporter groups before the match. According to information in TV4's broadcast, a Juventus supporter was taken to hospital with serious injuries.
The situation led Juventus to refuse to play the match, which also caused delays to other Serie A matches that evening. However, the other four matches were later able to start.
The derby is of great importance in the fight for the final places in next season's Champions League, with Juventus, Milan, Roma and Como competing for the two remaining places.
