New signing Marco Cassetti could be in contention to make his debut when Watford entertain Birmingham.
The 35-year-old former Roma defender arrived on Thursday on a season-long loan from Udinese, becoming the fifth player to do so this summer as the Hornets continue to utilise their links with the Serie A club, who are also run by Watford's new owners the Pozzo family.
Captain John Eustace will be assessed after a back injury ruled him out of Tuesday's last-gasp 1-0 home defeat to Ipswich.

Summer signings Fitz Hall and Alex Geijo have not yet made their debuts and are unlikely to feature once more, while midfielder Stephen McGinn continues to be eased back in on his return from a lengthy knee injury and is also yet to get a run out.
Nikola Zigic is likely to start as Blues head to Hertfordshire searching for their first league win of the season.
The towering Serbian, linked with a possible move to Spanish side Real Mallorca, stepped off the bench to snatch a point against Charlton last weekend before doing so again in midweek, although his goal was not enough to prevent a 3-2 defeat at Sheffield Wednesday.
Manager Lee Clark is now expected to include Zigic from the off at Vicarage Road and the frontman will likely partner Marlon King in attack.
On-loan midfielder Ravel Morrison was dropped at Hillsborough and will be pushing for inclusion against the Hornets.
Right-back Stephen Carr continues to be assessed having not yet featured this season due to a thigh injury.
