Neil Lennon has revealed that Celtic defender Jozo Simunovic will be out until next year following a clean-up of his knee.
The 25-year-old Croatian has been sidelined since the Hoops' 2-0 victory over AIK on August 22.
It was reported that he was expected to miss another three weeks following his operation earlier in the month but ahead of the trip to Hibernian in the the Scottish Premiership today, the Parkhead boss said: "You are probably looking at three to four months.
"It was a clean-up and he knows what to do for his rehab and we are just discussing maybe if he can go away for a few weeks and do his rehab at home.
"He is alright. It is a blow for us and the player.
"He felt it was a necessity and thankfully it is not a micro-fracture again, which is a serious operation where you are out for six to eight months.
"He has had a clean-up and obviously we have to tread carefully on his rehab and the sooner we get him back the better."
Striker Leigh Griffiths remains out with an ongoing thigh strain as well as a virus. Griffiths' last appearance for Celtic was as a substitute against Hearts in August.
Lennon said: "Not only has he got a thigh strain, he has a bit of a virus at the minute."
Lennon was speaking at the club's Lennoxtown training complex just after it was announced that the league leaders will play Hibs in their Betfred Cup semi-final at Hampden Park on Saturday, November 2 with a 5.30pm kick-off.
