Watford will still be without Tom Cleverley for the visit of Swansea.
The on-loan Manchester United midfielder serves the final game of a three-match ban for his red card at Scunthorpe last month.
Jon Harley will therefore hope to keep his place, although Stephen McGinn is pushing to make his full debut after two substitute appearances following his recent switch from St Mirren.
Winger Will Buckley could be added to the squad for the first time since his move from Rochdale after recovering from a thigh strain.
Skipper Jay DeMerit came through 90 minutes at Derby on Saturday unscathed despite picking up a leg knock playing for USA in midweek.
Danny Graham should once again partner Heidar Helguson in attack.
Swansea midfielder David Cotterill will face a late fitness test.
The 22-year-old winger missed Saturday's controversial defeat at Nottingham Forest with a hamstring injury and he again remains a doubt although he will travel with the squad to Vicarage Road.
Cedric van der Gun appeared as a second-half substitute at the City Ground after a troublesome hamstring injury of his own and the Dutchman will be pushing for a start.
The Swans' lengthy injury list does not make pretty reading for boss Paulo Sousa as he continues to be without a plethora of first-team players.
Garry Monk (calf), Joe Allen (knee), Andrea Orlandi (hamstring), Jordi Lopez (ankle), Albert Serran (hamstring), Fede Bessone (calf) and Ferrie Bodde (knee) all remain sidelined and are unlikely to return in the near future, while Gorka Pintado serves the third instalment of his four-match suspension.
The Swans will be hoping to bounce back from their first defeat in 13 games at the weekend by claiming all three points and closing to within four points of third-placed West Brom.
