Watford appear to have no fresh injury concerns ahead of Tuesday's home clash with Premier League basement boys Norwich.
Nigel Pearson's 17th-placed Hornets came through seemingly unscathed on Saturday when they were beaten 3-0 at Chelsea, their third successive defeat.
Norwich will be without midfielder Todd Cantwell due to a hamstring strain.
Watford provisional squad: Foster, Gomes, Masina, Femenia, Holebas, Mariappa, Cathcart, Dawson, Kabasele, Cleverley, Chalobah, Hughes, Doucoure, Capoue, Quina, Penaranda, Pereyra, Sarr, Deeney, Welbeck, Pedro, Gray, Pussetto.
Norwich provisional squad: Krul, Aarons, Godfrey, Klose, Lewis, Tettey, McLean, Vrancic, Buendia, Duda, Hernandez, Drmic, Pukki, McGovern, Trybull, Rupp, Stiepermann, Martin, Idah.
