Crystal Palace are without a number of first-team players for the visit of Tottenham as they look to prevent an eighth straight defeat.
Alli has missed the last five games with a hamstring injury, while Dier has been suspended for the last four games – which Spurs have won all of.
That means midfielder Tanguy Ndombele (knee) is the only absentee.
Crystal Palace provisional squad: Guaita, Ward, Dann, Kelly, Mitchell, McArthur, McCarthy, Schlupp, Townsend, Ayew, Zaha, Hennessey, Woods, Kouyate, Milivojevic, Tavares, Meyer, Pierrick, Riedewald.
Tottenham provisional squad: Lloris, Vorm, Gazzaniga, Aurier, Sanchez, Alderweireld, Dier, Vertonghen, Cirkin, Davies, Sessegnon, Winks, Lo Celso, Sissoko, Fernandes, Skipp, Moura, Alli, Lamela, Son, Kane, Bergwijn.
