Celtic's Beram Kayal to miss rest of season
Celtic have confirmed that Beram Kayal will miss the rest of the season after the midfielder underwent ankle surgery.
The Israeli international was stretchered off following a challenge with Lee McCulloch during the 1-0 win over Rangers on 28 December.
The 23-year-old had surgery in London on Monday evening.
And a statement on the club website read: "Unfortunately, our worst fears have been realised and Beram will be out for at least four months."
Kayal joined Celtic from Maccabi Haifa in 2010 and in October signed a new contract to keep him at the club until 2015.
On Friday, manager Neil Lennon described the player's injury as a "huge blow" for the club.
"It's no coincidence that this run has coincided with Beram signing a new contract," he said.
"He is a pivotal player for us. But I will say one area we have real quality strength in depth is midfield. I've got plenty of cover in midfield.
"But no-one likes to lose a player for a concerted period of time. We have been unfortunate with these injuries."
Regarding the tackle between Kayal and McCulloch, Lennon said: "It was a good challenge between two committed players.
"The way his ankle has turned, he has got a bit of cartilage floating in there that might need attaching back in and there is ligament damage as well."
