Lloyd Doyley will miss Saturday's game with Burnley but Watford could welcome back fellow defender Marco Cassetti.
Doyley is out for around a week after twisting his ankle in the 4-1 win at Sheffield Wednesday.
Cassetti and Jonathan Bond both missed the game at Hillsborough but are fit once again and Essaid Belkalem is also in contention following his back spasm.
Watford continue to have a shortage of attacking players, with only two recognised strikers available.
Chu-Young Park is unlikely to return for another two or three weeks due to a toe injury and Fernando Forestieri suffered a small fracture on his toe so is likely to be sidelined for a further week to ten days.
Young Watford striker Bernard Mensah had an operation in Rome on Monday and is expected to be fit for pre-season.
Almen Abdi (foot) and Fitz Hall (Achilles) should be available after they played 45 and 77 minutes respectively in the midweek friendly with Northampton Town.
Watford are eight points below the play-off places with eight matches remaining. So with a game in hand, finishing in the top six is not completely out of the question, especially with several play-off chasing sides struggling for form.
Sannino said: "I think we need to carry on trying to win as many matches as possible until towards the end of the season. Then we will open our eyes to see if we are still dreaming of something or if we should be building towards next season.
"I am very practical. I don’t like to give a false expectation to people. I like to allow people to dream; to dream together. To have a surprise, we have to work."
He later added: "I am focused on the next game. I am not focused on this vision."
