Watford must wait on the fitness of Keinan Davis ahead of the visit of Coventry in the Sky Bet Championship on Saturday.
Davis missed Watford’s 2-1 win at Cardiff on Wednesday, but will be assessed along with Samuel Kalu.
Craig Cathcart, however, remains on the sidelines, with the medical staff focusing on his return to long-term fitness.
Kortney Hause is also continuing his recovery from a knee problem.
Coventry will make a late decision over the condition of Gustavo Hamer as the squad continues to struggle with illness.
Hamer suffered a dead leg during Coventry’s win over Blackburn on Tuesday.
Kyle McFadzean was withdrawn just before the midweek game with a fever and it remains to be seen whether he has recovered in time for the trip to Vicarage Road.
Liam Kelly also remains on the treatment table with a knee problem but is due to rejoin training from Monday.
