Wes Morgan has been ruled out of Leicester City's clash with Sunderland on Tuesday.
The Foxes captain has missed the last two Premier League games with a back injury and he has not recovered in time for the visit of the Black Cats.
As well as Morgan's absence, Leicester will have to cope without midfielder Nampalys Mendy as he continues to recover from an ankle problem.
"Unfortunately Wes Morgan and Mendy are still injured. Wes has trained on grass but won't be available tomorrow," said Foxes boss Craig Shakespeare.
However, while Mendy and Morgan are out of the match with Sunderland, winger Marc Albrighton is available for selection after missing Saturday's win over Stoke due to illness.
