Everton playmaker James Rodriguez and goalkeeper Jordan Pickford face late fitness tests ahead of the FA Cup fifth-round visit of Tottenham.
The Colombia international was taken off with a tight calf during Saturday's 3-3 draw at Manchester United, the second successive match England's goalkeeper missed due to a rib injury.
Midfielder Allan has returned to training after a hamstring injury which has sidelined him for almost two months but will not be available until the weekend, while new signing Josh King is cup-tied having already played for Bournemouth.
Dele Alli could return to the Tottenham bench.
The 24-year-old midfielder, who was keen to leave the club in January, has not played since the third-round win at Marine at the start of last month due to a tendon injury.
Serge Aurier (calf) is a doubt, while Sergio Reguilon (muscle) and Giovani Lo Celso (hamstring) are definitely out.
Everton provisional squad: Olsen, Coleman, Keane, Mina, Godfrey, Digne, Doucoure, Gomes, Rodriguez, Calvert-Lewin, Richarlison, Pickford, Virginia, Holgate, Nkounkou, Davies, Delph, Sigurdsson, Iwobi, Bernard.
