Allan has been left out of the Napoli squad for tomorrow’s Coppa Italia quarter-final against Lazio, officially due to a muscular issue.
The match is a one-off at the Stadio San Paolo on Tuesday at 19.45 GMT, with the winner decided after 90 minutes, extra time or even penalties.
None of the injured players who missed the 2-0 defeat to Fiorentina have recovered, so Dries Mertens, Kalidou Koulibaly, Nikola Maksimovic, Faouzi Ghoulam and Kevin Malcuit are still out.
Amin Younes has also picked up a knock and will not be taking part.
A bigger loss is Allan, officially due to a muscular issue, although he was already in the news after storming off down the tunnel after his substitution against Fiorentina.
There were also reports in the newspapers that the Brazilian had a tense argument with teammate Mertens in the dressing room.
We could see Gennaro Gattuso give Stanislav Lobotka his debut, while Diego Demme is tipped to start in midfield.
Napoli squad for Lazio: Karnezis, Meret, Ospina, Di Lorenzo, Hysaj, Luperto, Manolas, Mario Rui, Tonelli, Demme, Elmas, Lobotka, Fabian Ruiz, Zielinski, Callejon, Insigne, Leandrinho, Llorente, Lozano, Milik
