Watford stretched their unbeaten run to five games as they shared a scoreless draw with Huddersfield for the first time in their history.
The Hornets created few opportunities at John Smith's Stadium, although Yaser Asprilla tested Lee Nicholls at the start of the second half.
Huddersfield, who have now tasted victory just once in nine games, had the better of the first period but were unable to find a breakthrough.
The draw - the first between the sides in 17 meetings - means their league positions stay unchanged, with the Terriers 21st and Watford 16th.
