Morgan missed the 2-0 defeat to Barnsley on Monday through suspension following his red card in the home loss to Millwall three days previously.
Zak Whitbread replaced Morgan at centre-half at Oakwell for his first start since Boxing Day and he is likely to drop back out to accommodate the skipper's return.
Midfielder Danny Drinkwater will also come back into the reckoning after illness to give Foxes boss Nigel Pearson a full strength squad to choose from for a vital clash on the south coast.
Three defeats on the spin have seen Leicester drop out of the play-off places and they go into Saturday's game against Brighton, who occupy the final play-off spot, two points behind Albion.
