Fans unfurled a banner criticising the mother of a Napoli supporter who was killed in Rome last May in an incident on the fringes of the Italian Cup final.
The south stand, behind one of the goals, is where Roma's hardcore 'ultra' fans hold sway.
The banner read: "How sad: making money from death through books and interviews."
The banner was a clear reference to Antonella Leardi who recently published a book in memory of her son Ciro Esposito, who was shot dead during clashes between rival fans - although Napoli were playing Fiorentina in the Italian Cup final, some Roma fans had mobilised in a bid to cause trouble.
The Italian Football Federation (FICG) said the 'Curva Sud' stand will be closed for Roma's clash with Atalanta on April 19th.
