Dunfermline Athletic have confirmed that goalkeeper Paul Gallacher has been ruled out for the remainder of the season with a shoulder injury.
Gallacher, who has been first choice since arriving in June, was injured in the 4-0 defeat by Hearts last month.
Pars manager Jim McIntyre said: "We have had the results of his scan and it's obviously very disappointing.
"He's seeing a specialist today to see whether it will be operated on or not. His season is over."
It means a new goalkeeper has become a priority for McIntyre, who was already considering his options to cover for the loss of Jason Thomson.
The manager confirmed that the right-back will not be back at East End Park following the expiry of his loan spell from Hearts.
Gallacher, who has eight Scotland caps and was previously with St Mirren, has been one of the most consistent performers this season for the side sitting bottom of the Scottish Premier League.
And it leaves injury-hit Dunfermline with Chris Smith, who started in the two league fixtures since Gallacher was injured at Tynecastle on 24 December, as their only fit senior goalkeeper.
"We'll need to get a goalkeeper in," said McIntyre, whose side travel to face SPL rivals Inverness Caledonian Thistle in the Scottish Cup on Saturday. "We're looking at a couple of possibilities.
"I'm not going to discuss individuals. We've been thwarted in several attempts.
"We've tried to bring a couple of players in, but it's proved unsuccessful so far."
McIntyre distanced himself from newspaper reports suggesting that he has rekindled his interest in 26-year-old Raith Rovers striker John Baird, for whom Dunfermline had to offers rejected during the summer.
"John Baird isn't one of those players," the Pars boss added.
"I've definitely not made a move for John Baird."
