Leicester captain Wes Morgan trained with his team-mates on Monday on the eve of the club's crunch Champions League clash with Atletico Madrid.
Morgan missed the quarter-final first-leg match at the Vicente Calderon with an ongoing back problem as the Foxes were defeated 1-0 last week.
However, the club are hopeful that he will return to the side on Tuesday with Leicester going through a bit of a centre-back crisis at the moment.
Robert Huth is suspended for the game and Younes Benalouane limped off against Crystal Palace, despite Craig Shakespeare insisting the substitution was precautionary, with the Algerian suffering from cramp.
