Barnsley take on another Championship high-flyer after moving out of the relegation places with the win at home to Brighton & Hove Albion in midweek.
Watford themselves were beaten for the first time in eight league matches when they went down 2-1 at home to Blackpool.
Aside from the injured Scott Golbourne, the hosts have an almost full-strength squad to choose from for the second home game running.
Gianfranco Zola has a number of players at risk of suspension but is unlikely to make drastic changes to his side despite their defeat last time, and Manuel Almunia could return in goal.
