Pepe Reina and Gonzalo Higuain are in the Napoli squad flying to Swansea for the Europa League.
The Round of 32 first leg tie is on Thursday at 20.05 GMT at the Liberty Stadium.
Higuain was in doubt after hurting his back at the weekend and today the striker and Valon Behrami did not train with their teammates.
Goalkeeper Reina only trained in part with the others, but he too is included in the trip to Wales.
Defender Federico Fernandez is suspended, while Juan Camilo Zuniga and Giandomenico Mesto are long-term absentees.
Jorginho is not on the UEFA list after his January transfer from Hellas Verona, but will fly out with the squad to continue training.
Napoli squad for Swansea: Reina, Rafael, Colombo, Albiol, Britos, Henrique, Maggio, Ghoulam, Reveillere, Inler, Dzemaili, Behrami, Insigne, Callejon, Mertens, Hamsik, Higuain, Pandev, Duvan Zapata
