Napoli centre-back Kalidou Koulibaly is doubtful for their Serie A fixture against Udinese on Saturday, owing to a shoulder injury.
The 28-year-old fell heavily on his right shoulder during a training session on Thursday morning, according to Sky Sport Italia.
It is uncertain when the Senegal international will be available to play as he could also miss his side’s Champions League clash against Genk on December 10.
Koulibaly has made 17 appearances for Carlo Ancelotti ‘s men across all competitions this season, including 12 in Serie A.
