On 3 January 2013, the club was hosting A.C. Milan in a friendly, when a small group of people aimed chants at A.C. Milan players, including M'Baye Niang, Urby Emanuelson, Sulley Muntari and Kevin-Prince Boateng. Boateng reacted angrily, kicking the ball into the stands, before the Milan players walked off the field, causing the game to be abandoned. The final verdict on the incident, however, stated that the punishment handed down was not in reference to racism allegations. Pro Patria was forced to play one game behind closed doors because of this incident.
