Lazio's Giuseppe Sculli has been banned for one month and fined US$30,000 ($29,386) for having links with a group of Genoa fans who interrupted a league game last season.
The Italian football federation (FIGC) said on Tuesday that Sculli knew in advance that some fans of Genoa were preparing a protest during Genoa v Siena, which the visiting side from Tuscany won 4-1 on 22 April.
FIGC's disciplinary commission said Sculli received a telephone call and was texted ahead of the game by a leader of the hooligans, who had frequent contacts with him.
Riots on the stands and smoke bombs hurled on the pitch interrupted the game as fans asked for and obtained the jerseys of the home players, claiming they were not worthy of wearing them.
The 31-year-old striker was the only player to be sentenced of the 15 who were indicted along with club president Enrico Preziosi.
Police have banned more than 100 Genoa fans from stadiums.
Juventus has completed the signing of Federico Peluso from Serie A rival Atalanta for 4.8 million euros ($6.78 million).
