The goalkeeper has missed the last three games, the first two with concussion and the other with a groin problem, with Ron-Robert Zieler deputising for the Denmark international.
Midfielders Nampalys Mendy and Matty James are also out with ankle injuries, with Mendy expected to return to the squad at the end of the week.
Provisional squad: Schmeichel, Zieler, Simpson, Huth, Morgan, Wasilewski, Hernandez, Chilwell, Fuchs, King, Amartey, Drinkwater, Gray, Kapustka, Mahrez, Albrighton, Schlupp, Vardy, Ulloa, Okazaki, Musa, Slimani.
