Jamie Vardy and Jonny Evans have been ruled out for months with Leicester's injury problems growing.
Striker Vardy is not expected back until March after suffering a hamstring injury last month.
Evans has also had an operation to solve his own hamstring problem after limping off against Newcastle in December and is sidelined until April.
Boss Brendan Rodgers said: "Jamie will be out for a number of weeks. It's been unfortunate for him but we're looking at up to eight weeks. He'll be out for a period of time.
"His is the higher end of his hamstring, you are looking into March for Jamie. He doesn't need an operation and that was the only good news from it."
Evans has been plagued by a foot issue for almost a year but it is the hamstring injury which he suffered against the Magpies which will keep the Northern Ireland international out.
Rodgers added: "He has had an operation so he will be April, with his hamstring he needed that."
