Watford goalkeeper Daniel Bachmann looks likely to miss out this weekend because of a knee injury.
Forward Joao Pedro has overcome a similar issue, while defender Kiko Femenia should be fit after a muscle problem forced him off last weekend.
Newcastle will be without Joe Willock, who injured a toe in training and could miss the Magpies' next game as well.
Defender Jamaal Lascelles has a thigh problem and faces a couple of weeks on the sidelines.
Callum Wilson, Paul Dummett, Freddie Woodman and Jonjo Shelvey remain out.
LAWRO'S PREDICTION
Watford's results have been pretty up and down so far but they have six points from their first five games, which they will be satisfied with.
