Fiorentina and Cagliari will retire the number 13 shirt worn by defender Davide Astori after the Italy international died on Sunday, the Italian clubs said on Tuesday.
Astori, who made 289 Serie A appearances in 10 seasons, died of a sudden illness on Sunday at the age of 31.
He also played 14 times for the national team and joined Fiorentina on loan in 2015 before the club signed him outright one year later and he went on to become their captain.
He previously spent six seasons at Cagliari and one on loan at AS Roma.
“In honour of Davide #Astori’s memory, @CagliariCalcio and #ACFFiorentina have decided to retire the No. 13 shirt. #DA13,” Fiorentina said on Twitter.
Cagliari posted a similar message.
Astori was found dead in his hotel room on Sunday in Udine where Fiorentina had been due to play Udinese.
Serie A later postponed all Sunday matches.
Italian public prosecutors said on Monday they were to open proceedings to determine whether Astori’s death could be considered as manslaughter.
