Walter Gargano has left the Napoli camp ahead of tonight's game due to family issues, confirmed the club.
The Uruguayan midfielder was released from duty this morning because of undisclosed family matters.
The 26-year-old will therefore be unavailable for tonight's Serie A match against Cagliari.
There were reports Gargano would've been on the bench anyway, but he will return to Naples after international duty with Uruguay.
It is also confirmed that Coach Walter Mazzarri will be on the bench despite suffering from kidney stones over the last few days.
Kick-off at the San Paolo is at 19.45 UK time and a win would take Napoli within three points of leaders Milan.
