Italian fourth-tier side Pro Patria must play their next home league match behind closed doors after fans racially abused AC Milan's Kevin-Prince Boateng, the league said on Tuesday.
Boateng walked off the pitch in last week's friendly because of monkey chants and his team mates followed him, drawing widespread praise across the game.
An Italian lower league (Lega Pro) statement said the taunts were "clearly racial discrimination" and deserved an immediate one-game stadium ban.
Italian football federation president Giancarlo Abete, whose organisation has long battled racism among fans, told reporters that officials could act in the future before players have to.
"If it is necessary to suspend the game, we will do it to stop this phenomenon," he said.
