Leicester City defender Miguel Vitor is fit again and has been included in the Foxes squad.
Boss Sven-Goran Eriksson has no new injury worries and is expected to name the same starting line-up that beat Nottingham Forest on Monday.
MATCH PREVIEW
In-form Leicester are vying for a fifth win in seven league matches and have risen from the relegation zone to within five points of the play-off places since Sven-Goran Eriksson took over as manager.
Watford have been been heading in the opposition direction, slumping to 15th in the table following a poor run of results. The Hornets are without a win in seven matches and are now only four points above the relegation zone.
Leicester have lost on only one of their last 10 visits to Vicarage Road. History and the form book are on the Foxes' side, and both also suggest that goals are on the cards.
The two games between these sides last season produced a total of 11 goals, and Championship matches involving Watford this season have produced 62 goals. Only Leeds' games have yielded more.
