Leicester boss Craig Shakespeare will refuse to gamble on Wes Morgan's fitness to keep their Champions League dream alive.
The skipper is definitely sidelined for Saturday's Premier League trip to Crystal Palace with the back injury which has seen him miss the last five matches.
The Foxes host Atletico Madrid in Tuesday's quarter-final second leg, having lost 1-0 in Spain on Wednesday, with Robert Huth banned and Yohan Benalouane their only available centre-back.
But despite his defensive issues Shakespeare is not prepared to risk centre-back Morgan if he fails to prove his fitness.
