Fiorentina, Catania and Napoli are leading Italian football's efforts to raise money for the victims of the earthquake in L'Aquila.
The Lega Calcio has announced a minute's silence ahead of every game in Serie A, B and the Primavera League this weekend and all players will wear a black armband, as will Udinese in Thursday's UEFA Cup quarter-final with Werder Bremen.
Clubs are looking for ways to raise money for the victims of the earthquake, as Napoli, Siena and Catania have confirmed they will donate the gate receipts from their next home games.
Fiorentina defender Luciano Zauri, who is from the Abruzzo region hit by the quake, said: "My teammates immediately made themselves ready to help.
"I have something in mind that goes beyond simply raising funds, but it will take a few days to organise.
"After years in football I have the contacts to do something important for my home region."
