Six Pro Patria fans have been given jail sentences, ranging from 40 days to two months, following their racial abuse of Kevin-Prince Boateng during a friendly against AC Milan in January.
Boateng made the headlines at the beginning of the year when he, along with his Milan team-mates, walked off the pitch after receiving abuse from supporters of the fourth-tier side.
The Rossoneri had played just over 25 minutes of the game when the Ghanaian kicked the ball towards the opposition fans, took off his shirt before leaving the field of play.
Milan players Urby Emanuelson, Sulley Muntari and M'Baye Niang were also targeted by the Pro Patria supporters.
According to the ANSA news agency, one fan was hit with a 40-day sentence after collaborating with authorities, while the remaining five received two-month sentences. Prosecutors had originally requested for sentences of four to six months.
The six supporters were also fined a total of $13,000, plus trial expenses.
Since the incident at Pro Patria, Boateng has been named as part of FIFA's new anti-racism Task Force, while he also met with FIFA president Sepp Blatter to discuss ways of dealing with racism in football.
FIFA has decided to crack down on the problem, approving new strict regulations to combat racism last week.
