Celtic boss Brendan Rodgers revealed Craig Gordon is "highly unlikely" to face Aberdeen on Sunday but is confident of having him back for the William Hill Scottish Cup final.
The Hoops keeper has missed the last two games with a knee problem with Scott Bain again deputising in the goalless draw against Kilmarnock on Wednesday night.
The champions will be presented with their Premiership trophy after the game against the Dons in what is sure to be a sell-out Celtic Park before they start preparing for the showpiece finale against Ulsterman Steve Robinson's Motherwell at Hampden Park tomorrow week, as they look to complete an unprecedented successive treble.
Asked if he was confident that Gordon would be ready for the final against Well, Rodgers said: "Yes. It was just a case of getting Scott some game time as well and letting Craig try to give it every possible chance because he is a big player for us.
"Our plan was to close him down for the three games this week and see how he is at the beginning of next week," added Rodgers.
Bain gave Celtic a boost on the eve of the final regardless of Gordon's status by signing a permanent four-year deal from Dundee.
The 26-year-old has made six loan appearances so far and said: "I'm delighted, it's more than I expected when I came in. I'm over the moon."
Ulsterman Rodgers also expects striker Leigh Griffiths to be available for the Aberdeen match after missing the last two matches with illness.
"He should be (back), yes," said Rodgers. "He is back in training and hopefully available for the weekend," added the Carnlough native.
