Celtic captain Scott Brown is out of the Champions League last-16 second-leg tie with Juventus due to a hip injury.
The Hoops' skipper is waiting to hear from a specialist about a long-term abductor problem and whether he will need surgery on it.
His side will carry a 3-0 deficit to Turin and Brown's absence will significantly hamper their already slim hopes of qualifying for the quarter-finals.
When asked if Brown was definitely out, Celtic boss Neil Lennon said: "Oh yes I would imagine so. He is out indefinitely. We are still waiting to hear from the specialist, whether he requires surgery or not and I am hoping we will get a definitive answer by the end of the week."
The 27-year-old will also miss Scotland's World Cup qualifying double-header with Wales and Serbia in March.
Lennon confirmed he will also be without full-back Mikael Lustig with a thigh injury, but hopes Charlie Mulgrew will recover from a glute injury to play against the Italian league leaders.
