The Foxes hold a slender 1-0 advantage going into the second leg of the play-off semi-final after striker David Nugent ended his barren spell with the only goal.
Paul Konchesky returned from a minor hernia operation and was on the bench for the first leg. A possible change could see him recalled at left-back at the expense of Jeff Schlupp.
Ritchie De Laet (calf) came through the Hornets clash unscathed and will keep his place.
Loan duo Michael Keane and Harry Kane are free to play in the play-offs.
