Fernando Forestieri and Lewis McGugan both returned to training this week and could be in contention for Tuesday night’s Championship game at Doncaster Rovers.
Forestieri has missed Watford’s last three matches with a hamstring strain while McGugan last played on January 18 after suffering a thigh injury.
The Hornets pair will both have their fitness assessed ahead of the game at Keepmoat Stadium.
Two players who could be ruled out however are Arsenal loanee Chu-Young Park, who picked up a thigh injury while in action for South Korea on Wednesday night, and Samba Diakite who twisted his knee in training.
Diakite has been absent for the last three matches while he served a suspension for a red card he received against Middlesbrough last month.
Watford have still not given an update on the fitness of Almen Abdi despite the club claiming the midfielder’s situation would be clarified in early February.
The midfielder has not started a match since August due to an ongoing foot problem.
Fitz Hall is also expected to miss Tuesday’s match with an Achilles injury.
