Leicester defender James Justin is set to miss the rest of the season after damaging knee ligaments.
Justin, who has made 31 appearances in all competitions for Brendan Rodgers' side this season, was carried off on a stretcher after landing awkwardly.
"The scan hasn't shown up so well, it's a massive blow for us," said Rodgers.
"He's been incredible for us, played in so many positions and been a minimum eight out of 10 in all of them.
"He's tough mentally and physically, that's what makes him the boy he is.
"It will make him stronger.
