Napoli have confirmed Kostas Manolas has suffered a first-degree muscle injury.
The Partenopei defender was replaced by Nikola Maksimovic after 15 minutes of the 2-1 win against Udinese in Serie A last weekend.
The Azzurri confirmed the Greek defender has suffered a muscle injury.
“Kostas Manolas, who was substituted after 15 minutes on Sunday’s match against Udinese in Friuli, underwent instrumental tests this morning at the Pineta Grande Clinic,” the club said in a statement.
“It showed a first-degree injury of the right external obturator muscle.”
Napoli face Empoli at the Stadio Maradona in the Coppa Italia tomorrow, before hosting Fiorentina in Serie A on Sunday.
