Mousa Dembele is struggling with a foot injury ahead of Tottenham's visit to West Brom on Saturday.
Dembele had just recovered from a hamstring strain when his left foot was stamped on in training.
The Belgian is now a doubt for this weekend's trip to The Hawthorns.
Harry Kane remains sidelined with an ankle ligament injury while the likes of Son Heung-min and Erik Lamela will be assessed following long excursions on international duty.
Provisional squad: Lloris, Vorm, Lopez, Walker, Trippier, Alderweireld, Vertonghen, Carter-Vickers, Wimmer, Rose, Davies, Dembele, Dier, Winks, Wanyama, Carroll, Onomah, Sissoko, Nkoudou, Alli, Lamela, Eriksen, Son, Janssen.
