Everton caretaker manager Duncan Ferguson has to contend with the same injury problems faced by the sacked Marco Silva as he seeks to halt their slump against Chelsea at Goodison Park.
There is also a doubt over defender Yerry Mina who limped away from Anfield after the Merseyside derby defeat which cost Silva his job.
Tammy Abraham should shake off a knock to feature for Chelsea.
The in-form England striker limped out of the closing stages of Wednesday's 2-1 home league win over Aston Villa, but is expected to be ready to take on the Toffees.
Everton provisional squad: Pickford, Sidibe, Holgate, Keane, Digne, Davies, Schneiderlin, Bernard, Iwobi, Sigurdsson, Richarlison, Lossl, Baines, Mina, Walcott, Tosun, Kean, Calvert-Lewin.
Chelsea provisional squad: Arrizabalaga, Zouma, Emerson, James, Tomori, Kovacic, Willian, Kante, Pulisic, Abraham, Hudson-Odoi, Mount, Batshuayi, Caballero, Christensen, Azpilicueta, Gilmour, Jorginho, Barkley, Pedro, Giroud, Cumming.
