Defender Miguel Britos is expected to be available following a groin injury when Watford travel to Middlesbrough in the Premier League.
Younes Kaboul could continue in central defence as Craig Cathcart remains out with a groin injury, while midfielder Valon Behrami is a minor doubt with an undisclosed knock.
Forward Isaac Success, who scored his first Watford goal prior to the international break, could be handed his first start. Daryl Janmaat (shoulder) is still out.
Provisional squad: Gomes, Gilmartin, Pantilimon, Mariappa, Kaboul, Britos, Prodl, Holebas, Zuniga, Kabasele, Amrabat, Behrami, Capoue, Guedioura, Watson, Doucoure, Pereyra, Deeney, Success, Ighalo.
