Bristol City travel to Vicarage Road on Saturday looking to inflict a fourth straight defeat upon Watford.
Sean Murray could come back into the midfield for Gianfranco Zola's men after sitting out Tuesday's 1-0 defeat against Brighton & Hove Albion.
Marco Cassetti is a doubt, as he is suffering from a minor concussion, but Troy Deeney could feature for the Hornets following his release from prison.
Alex Geijo (groin), John Eustace (back), Prince Buaben (thigh) and Geoffrey Mujangi Bia (groin) all look likely to miss out.
Meanwhile, Derek McInnes will be without Greg Cunningham and Cole Skuse, who have been sidelined with ankle injuries.
Mark Wilson is back fit and could be preferred to Richard Foster at right-back.
Current form:
Watford: LWLLL
Bristol City: LWWLW
Possible lineups:
Watford: Almunia; Doyley, Dickinson, Nosworthy, Pudil; Hogg; Yeates, Abdi, Murray; Iwelumo, Deeney
Bristol City: Heaton; Wilson, Fontaine, Carey, Edwards; Anderson, Woolford, Pearson, Adomah; Baldock, Stead
Sports Mole says: 2-1
