Celtic left-back Emilio Izaguirre will be out of action for between four and six months after fracturing his right ankle during Sunday's victory at Aberdeen.
Izaguirre was carried off on a stretcher after going down in agony following a sliding challenge from Peter Pawlett. Hoops boss Neil Lennon revealed tests had shown up a fracture, with the club later confirming it would require surgery.
A statement on Celtic's website read: "Emilio Izaguirre will be out of action for between four to six months after suffering a fracture to his right ankle.
"The Honduran defender was injured during the first half of Celtic's match against Aberdeen at Pittodrie today, which the Hoops won 1-0 thanks to an Anthony Stokes goal.
"Following an investigation in hospital, the club can confirm that Emilio has a fracture to his right ankle which will require surgery. This will be carried out later this week and Emilio will be out of action for between four to six months.
"The thoughts of the Celtic family are with Emilio and everyone wishes him a speedy recovery from injury."
