Hornets stung by Forestieri absence
Watford are without Fernando Forestieri for the visit of Nottingham Forest.
The Italian striker has been absent with a hamstring problem for the last two games, during which time the Hornets have picked up just one point.
Midfielder John Eustace and defender Nyron Nosworthy both returned to training this week after injury but the pair are some way short of match fitness and will not be involved.
Defender Lloyd Doyley remains sidelined with a calf injury.
Boss Gianfranco Zola picked Alex Geijo alongside Troy Deeney in attack for the 1-1 draw at Burnley, but could recall Matej Vydra to face Forest.
The Hornets are three points behind Millwall in sixth, but will be leapfrogged by their opponents if they suffer a second successive home defeat.
Simon Cox could return to the Forest squad.
Cox has been out for almost a month with a foot injury but after a full week's training the Republic of Ireland international striker is pushing to be included in manager Sean O'Driscoll's plans.
On-loan Chelsea defender Sam Hutchinson and borrowed Tottenham midfielder Jermaine Jenas are back in training after respective knee and calf injuries but neither player is likely to be risked at Vicarage Road.
O'Driscoll has the likes of defenders Elliott Ward and Greg Halford and midfielders Simon Gillett, Lewis McGugan, Henri Lansbury and Radoslaw Majewski available should he wish to make any changes from the side that drew 0-0 at Brighton last weekend.
