Tom Cleverley is a doubt ahead of the Hornets trip to face Leicester at the King Power Stadium.
Cleverley was substituted before half time of the game against Southampton and will be given until today to prove his fitness
Silva said: “He felt a minor problem, a small injury in the last match. He is still in doubt, a doubt for the next game. We have one more session tomorrow and we’ll see how his physical condition is and then I’ll take a decision. It’s a small injury in his hamstring, nothing special.”
There were no other injuries picked up after last Saturday’s game against Southampton.
