Watford's play-off bid suffered a further blow as they were held to a goalless draw at home by Preston.
Their best chance came mid-way through the second half as Ismaila Sarr volleyed just wide from a Ken Sema cross.
Joao Pedro also saw an effort well saved low down by Preston goalkeeper Freddie Woodman but it was an immensely frustrating afternoon for the Hornets.
Preston could have pinched victory with Alvaro Fernandez and Ched Evans forcing first-half saves from Daniel Bachmann.
