Isaac Success is fully recovered from injury and January signing Mauro Zarate is also available for the first time having served out a suspension, Walter Mazzarri has confirmed, with Jose Holebas in contention again after a ban of his own.
This will be the first top-flight meeting between Watford and Burnley at Vicarage Road.
The Hornets are unbeaten in their last five home PL matches against newly-promoted sides (W2 D3) without conceding a single goal.
Burnley have only one point from their 10 PL away matches this season (W0 D1 L9), scoring four goals.
Troy Deeney has scored in each of his three league appearances against Burnley at Vicarage Road.
Walter Mazzarri: "We need to play the same against Burnley as we did against Arsenal. We have to see Burnley as if we are playing Arsenal or Chelsea."
Sean Dyche on Brady and Westwood: “They are fit and well so they are in contention for what we do, certainly as a squad, because they have both been playing actively."
