The on-loan Chelsea defender has missed the last two matches with a groin strain but he has trained this week and Sven-Goran Eriksson is confident he will be available.
Otherwise, the Foxes are as they were with Bruma`s Chelsea team-mate Patrick van Aanholt and veteran striker Steve Howard still sidelined with thigh and ankle problems respectively.
Eriksson has options should he wish to make changes, with defenders Julio Moreno and Bruno Berner, midfielders Matt Oakley and Lloyd Dyer and striker Martyn Waghorn all available for recalls.
Yakubu could be in line to face his former club. The Nigerian played for Pompey between January 2003 and July 2005.
