All of Sunday's Serie A fixtures have been postponed following the shock death of Fiorentina captain Davide Astori at the age of 31.
The Italy international was found dead in his hotel room during the early hours of this morning, caused by a "sudden illness".
Fiorentina's meeting with Udinese was immediately called off, and six other matches - including this evening's Milan derby - have also now been adjourned until a later date.
Genoa were due to host Astori's former club Cagliari in the early kickoff at 11.30am, with many of the defender's former teammates being left in tears once the news had filtered through.
Astori spent 12 years of his career in Serie A, half of which came with Cagliari.
