Torino defender Angelo Ogbonna has withdrawn from the Italy squad ahead of the World Cup qualifying matches against Armenia and Denmark.
The 24-year-old was included in a 27-man squad named by Cesare Prandelli on Sunday night, but an inflamed prostate gland has forced the centre-back out of contention.
AC Milan defender Ignazio Abate sat out training in Coverciano on Monday, due to a cold, with Paris St Germain midfielder Marco Verratti still nursing a bruised foot.
Prandelli has yet to announce a replacement for Ogbonna ahead of Friday night's Group B game against Armenia at the Hrazdan Stadium in Yerevan.
On Tuesday, the Azzurri welcome Morten Olsen's Denmark to the San Siro in Milan.
