Watford boss Javi Gracia is confident Roberto Pereyra will be fit for their FA Cup semi with Wolves.
Pereyra is carrying a hip injury this week.
The skilful Argentina international has played a key role in Watford's successful season and boss Gracia is confident he will be given the green light to play.
"Pereyra felt some pain but I think he can be ready for the next game," said Gracia, who withdrew the 28-year-old at half-time against Fulham as a precaution.
"Roberto is an important player for us but if he is not available I have other players ready and waiting for the chance to play."
