Norwich boss Daniel Farke will check on Grant Hanley's fitness ahead of Saturday's visit of Tottenham.
The defender has only recently returned from four months out with groin and hernia problems and Farke is unsure if the skipper can play his third game in a week.
Son is serving the second of his three-match ban while Sissoko and Winks serve one-match bans for picking up five yellow cards.
Norwich provisional squad: Krul, Fahrmann, McGovern, Aarons, Zimmermann, Hanley, Byram, Lewis, Hernandez, Cantwell, Trybull, Tettey, Amadou, McLean, Pukki, Vrancic, Buendia, Stiepermann, Srbeny, Pukki.
Tottenham provisional squad: Gazzaniga, Vorm, Aurier, Walker-Peters, Alderweireld, Sanchez, Tanganga, Vertonghen, Rose, Dier, Ndombele, Wanyama, Skipp, Eriksen, Lo Celso, Sessegnon, Moura, Dele, Kane, Parrott.
