Brighton forward Aaron Connolly is available after missing last weekend's win over Burnley for personal reasons.
Danny Welbeck and Tariq Lamptey remain out because of hamstring problems, while Joel Veltman is self-isolating.
Josh King has recovered from a groin problem and could make his Watford debut.
Defender Kiko Femenia is in contention again but Juraj Kucka, Ozan Tufan, Joao Pedro and Nathaniel Chalobah will all miss out.
LAWRO'S PREDICTION
Both these sides were winners on the opening weekend but it is Brighton who I think will build on that here.
Watford surprised me against Villa but I don't see them getting too many points on the road.
