Giampaolo Pazzini, Dejan Stankovic and Douglas Maicon are in Inter's squad to face Napoli.
Pazzini was a major doubt to feature after spraining his ankle during Tuesday's 3-2 Champions League victory against CSKA Moscow.
He had initially been ruled out, but the ankle recovered quicker than expected and he is in the squad, although it remains to be seen whether he'll play.
Stankovic has been out of action for several weeks with muscular problems and is ready, while Maicon receives his first call-up of the season following surgery.
Andrea Ranocchia is suspended, while the injury list still includes Wesley Sneijder, Thiago Motta, Emiliano Viviano, Ivan Cordoba and Andrea Poli.
Inter squad: 1 Julio Cesar, 12 Luca Castellazzi, 21 Paolo Orlandoni; 6 Lucio, 13 Maicon, 25 Walter Samuel, 26 Cristian Chivu, 42 Jonathan, 55 Yuto Nagatomo; 4 Javier Zanetti, 5 Dejan Stankovic, 11 Ricky Alvarez, 19 Esteban Cambiasso, 20 Joel Obi, 29 Philippe Coutinho, 77 Sulley Muntari; 7 Giampaolo Pazzini, 9 Diego Forlan, 22 Diego Milito, 28 Mauro Zarate, 30 Luc Castaignos
