The defender missed Tuesday's disappointing 1-0 defeat at Millwall due to a one-match ban following his red card in last weekend's 3-2 loss at Peterborough.
Otherwise, manager Gianfranco Zola boasts the same squad as the one turned over at The Den.
Fit-again midfielder John Eustace is still lacking match fitness after his long-term back injury, while defenders Fitz Hall (hamstring), Nyron Nosworthy (Achilles), Neuton (dislocated shoulder) and Tommie Hoban (ankle) all remain sidelined.
The third-placed Hornets could see their lingering hopes of an automatic promotion place all but mathematically extinguished should Hull, six points better off with three games remaining, beat already-relegated Bristol City at the KC Stadium on Friday night.
