An injury to Christian Maggio has added to Napoli's problems ahead of Sunday's trip to Parma.
The Italy international strained and contracted a muscle in training, which was already fatigued.
He is expected to miss the weekend's action and gives Walter Mazzarri a selection headache.
Andrea Dossena and Salvatore Aronica are both out suspended.
Hugo Campagnaro is also still recovering from injury after pulling up in training on Wednesday.
Mazzarri will test Juan Zuniga on the right and Luigi Vitale on the left.
