Simon Cox returns after a month out through injury to start up front for Nottingham Forest for their trip to Watford.
He partners Billy Sharp, while the on-loan pair of Sam Hutchinson and Jermaine Jenas miss out with respective injuries.
Gianfranco Zola has opted for just the one change to his lineup from the 1-1 draw at Burnley, with Matej Vydra a direct replacement for Alexandre Geijo up front.
Watford: Almunia; Ekstrand, Hall, Hoban; Cassetti, Hogg, Chalobah, Abdi, Pudil; Vydra, Deeney
Forest: Camp; Hutton, Ayala, Collins, Ward; Harding, Cohen, Moussi, Reid; Cox, Sharp
