Watford are still missing nine players for their final home match of the season, including Kiko Femenia, Josh King, Tom Cleverley, Ismaila Sarr and Emmanuel Dennis.
Hassane Kamara is available following suspension, while Joao Pedro is expected to feature.
Leicester City defender Wesley Fofana is available after he was ruled out of the win against Norwich City due to a tight calf.
Ricardo Pereira remains out.
LAWRO'S PREDICTION
Leicester look a totally different team now Jamie Vardy is fully fit and finding some form.
He makes the pitch bigger for the Foxes' creative players too because opposing centre-backs take a couple of steps backwards because of his pace, which opens things up more for the likes of James Maddison to get on the ball.
