Hornets boss Malky Mackay has no fresh injury concerns for the visit of his former club Norwich.
Mackay - manager of the month for March - saw his side beaten 2-1 at home by Hull on Saturday to leave Watford eight points short of the play-off zone.
Full-backs Lloyd Doyley (knee) and Lee Hodson (ankle) are now both fully fit while fellow defender Adrian Mariappa returned to the side at the weekend after suspension.
Striker Troy Deeney has been struggling with illness but was back as a late replacement, while on-loan Manchester United midfielder Danny Drinkwater is also in the squad after recovering from his thigh injury.
Midfielder Stephen McGinn is a long-term absentee with a serious knee injury.
Canaries midfielder Wes Hoolahan will again be assessed before the trip.
Hoolahan missed out on the 3-0 defeat at Swansea on Saturday with a hamstring injury but is close to a return and manager Paul Lambert will give him as long as possible to prove his fitness.
Midfielder Korey Smith put in a bright performance from the bench at the Liberty Stadium and could be considered from the off as the Canaries look to avoid back-to-back defeats for the first time under Lambert.
Aaron Wilbraham will play no further part in the Canaries' push for promotion after being ruled out with a back injury while fellow striker Chris Martin is close to a return after two months out with a hamstring injury.
However, Dani Pacheco is set to partner captain Grant Holt in attack, again leaving Simeon Jackson on the bench.
