Ireland and Leicester left-back Greg Cunningham, on loan from Manchester City, suffered a broken leg after in his side's 1-0 victory over Hull City this Saturday.
Galway born Cunningham suffered the break as a result of Liam Rosenior's late tackle on 62 minutes, which earnt him a red card.
Leicester manager Sven-Goran Eriksson commented: 'It's a broken tibia, which could mean he is probably away for four months. He is in hospital right now and I guess he will undergo an operation today or tomorrow.
'It is important to say that as far as Rosenior was concerned, it was not stupid. It was bad luck and he didn't mean to do it, so there should be no shadow over him.'
Hull manager Nigel Pearson insisted there was no malice in Rosenior's tackle on Cunningham: 'It is obviously regrettable and you never like to see players have a serious injury. We wish the player a speedy recovery.
'Liam's distraught; it was just slightly mistimed with two players going for the ball. It would be wrong of me to complain about something like the red card and I have no complaints about it.
'It was very unfortunate as it didn't look ridiculously high.
'There was no malice in the challenge. If you know the player you'd be very aware of that.'
