Thomas Rogne is out of Celtic's Clydesdale Bank Premier League clash with Hearts at Parkhead.
The Hoops defender sustained a hamstring injury in last week's 1-0 defeat at Dundee United and has failed to recover.
Winger James Forrest (ankle) and midfielder Ki Sung-yueng (hamstring) are still out.
Boss Neil Lennon is expecting Hearts to have their Hampden heads on.
The Jambos are gearing up for their William Hill Scottish Cup final against Edinburgh rivals Hibernian at the national stadium next week but before that finish their league campaign with a game against the champions, who they beat in the cup semi-final last month.
Lennon, who will get his hands on the SPL trophy at the end of the game for the first time as a manager, believes it is almost inevitable that the Gorgie players will have one eye on their next trip to Glasgow.
"They have a cup final and it is a huge game," he said.
"They are starting to build momentum towards that. For everyone in Edinburgh and for neutrals all round the country, it is a game everyone is looking forward to.
"They will be competitive, I'm sure, but I would imagine the cup is at the forefront of their minds at the minute.
"Obviously we want to win the game and finish the season with a bit of style but ultimately it's just about the supporters enjoying themselves.
"We will probably go with a strong squad because I think everybody will want to play and finish off the season on the pitch if they can - although I can only play 14."
Hearts are set to shuffle their side with the final in mind.
Striker Craig Beattie (hamstring) could return at Parkhead after missing the last two matches.
Ian Black continues to nurse a hernia which is set to require surgery come the end of the season, when the midfielder is poised to leave the club, while Jamie Hamill (knee) is out.
First team coach Gary Locke believes a turbulent seasoncan be hailed a success if Europa League football is secured.
Hearts travel to Parkhead seeking to consolidate their fifth-placed position in the standings ahead of St Johnstone, who host Rangers.
After a season punctuated by wage delays and off-field uncertainty, first-team coach Gary Locke insists fifth place would be a success, with the possibility more could follow next week.
"It's been a bit of a rollercoaster, but getting into the top six was a great achievement for us," Locke said.
"Our target at the start of every season is to try to do well in the cup competitions and to get into Europe.
"We've got a chance of Europe, we're in the cup final, so from my point of view it's been a fantastic season.
"It's been a great team effort. We've had our ups and our downs but we've all stuck together. Hopefully we can finish on a high."
