The Giudice Sportivo has given Atalanta a suspended order to close their Curva Nord for one match.
The decision comes in the wake of the events at the Stadio Atleti Azzurri yesterday, where La Dea fans threw bananas at Milan player Kevin Constant during the match between the two teams.
They were also found to have shouted racist abuse at other black Rossoneri players, but because it is a first time offence by the club they escape with light punishment.
Elsewhere, Juventus’ Giorgio Chiellini has been banned for three Serie A matches after video replays showed him to have elbowed Roma’s Miralem Pjanic during Sunday’s game at Stadio Olimpico.
The Giallorossi have not escaped punishment either. They have been fined €50,000 after their fans were ruled to have taken part in vulgar chanting during the same match.
