Results went the Foxes' way on Saturday, securing them promotion with six games of the season to spare.
There's still plenty to play for as they want to secure the league title and go into Tuesday's game nine points better off than second-placed Burnley.
Brighton, meanwhile, were the last side to beat Leicester in the league on December 7 and will have to end a winless run of five games to do the double over the Foxes.
Despite their recent slump in form, Oscar Garcia's Seagulls are still in the hunt for a playoff place and go into Tuesday's game five points adrift of Reading in sixth.
Bruno Saltor serves the second of his two-game ban, so Inigo Calderon is likely to continue at right-back. Further forward, Craig Mackail-Smith could start after making his long-awaited return from the bench in Saturday's goalless draw with Barnsley.
Possible starting lineups
Leicester: Schmeichel; De Laet, Morgan, Moore, Schlupp; Knockaert, Drinkwater, James, Mahrez; Wood, Nugent
Brighton: Kuszczak; Calderon, Upson, Greer, Ward; Andrews, Stephens, Forster-Caskey; Rodriguez, Lingard; Ulloa
