All seven Serie A matches on Sunday have been postponed following the death of Fiorentina captain Davide Astori.
The club announced the 31-year-old had died early on Sunday, just hours before they were due to face Udinese away from home.
That game was called off after the news, while the match between Genoa and Cagliari, scheduled to kick off at 1230 local time, was also postponed shortly before it was due to begin.
A statement posed by Serie A's official Twitter account later said: "All matches scheduled for today [Sunday] are postponed, as a sign of mourning."
