Wilfred Ndidi will be out of action until at least next month after Leicester manager Brendan Rodgers confirmed the midfielder would have an operation on Thursday.
The Nigeria international has been a key man for Leicester this term but boss Rodgers revealed before the Carabao Cup clash with Aston Villa that Ndidi had been injured in training on Tuesday.
Rodgers said: ‘He took a knock in training on Tuesday. Unfortunately, he might need to have a slight operation tomorrow [Thursday] which will put him out for a few weeks. That’s just unfortunate.
‘But it’s not overly serious. Hopefully into February, he will be fit and ready to go again.’
Rodgers reacted by changing his formation against Villa on Wednesday evening, moving to a three-man defence.
Hamza Choudhury and Dennis Praet are likely to be the beneficiaries of Ndidi’s absence, with Praet chosen alongside Youri Tielemans in the centre against Villa.
