Dimitris Giannoulis and Josh Sargent could come back into contention for Norwich after missing the defeat at Arsenal with minor injuries.
Watford full-back Kiko Femenia has returned to training following a hamstring injury and will be assessed.
Goalkeeper Ben Foster has overcome a similar problem but this game comes too soon for striker Joao Pedro, who is nearing a comeback from a knee issue.
LAWRO'S PREDICTION
Norwich have one goal and no points from their first four games, while Watford are on a run of three straight defeats.
It's already pretty obvious that both of these sides are going to be down there scrapping at the bottom of the table so that makes getting something out of this game even more important for both of them.
