PARMA, Italy (AP) _ A fan was stabbed outside a stadium after a game Sunday, the latest violent episode in Italian soccer.

The 27-year-old man was taken to a hospital with wounds to his chest and ear.

The ANSA news agency reported that he had been scuffling with AC Parma fans just after the Serie A game ended, with first-place AS Roma rallying to win 2-1.

Before the game, fans from both teams clashed with each other and authorities. A police officer was hit in the face with a rock, and police fired tear gas to separate rival fans.

There were also fights before Sunday's Serie B game between Cagliari and Treviso, with nine police officers reportedly sustaining minor injuries.

In December, Serie A and B players forced symbolic 15-minute game delays before kickoff to protest the continuing violence inside and outside Italian stadiums. The protest came after a Molotov cocktail was thrown at the Internazionale team bus.
