The Israel international underwent ankle surgery last night. Kayal has been out of action since the 1-0 victory over Rangers last month.
A statement on Celtic’s official website read: “Beram Kayal underwent surgery last night on his injured ankle and the club can confirm that, unfortunately, our worst fears have been realised and Beram will be out of action for at least four months.”
“This is very sad news for Beram,” said Celtic boss Neil Lennon. “He has been brilliant for us and instrumental in our performances during the season.
“He will definitely be a big loss for us, but more importantly we are disappointed for him to be missing such a large part of the season at a time when he was playing so well.
“Clearly his health and fitness is now our priority and we will be making sure he gets our total support during the coming period.”
