Hearts will be without goalkeeper Marian Kello for up to six weeks with a hand injury picked up in training.And French striker Christian Nade will also not feature against Aberdeen on Saturday following his dressing-room bust-up with team-mate Ian Black.
Nade was due back in Edinburgh on Thursday after being allowed to return to his homeland for family reasons.
Hearts have invited the striker and a representative to attend a meeting next week to give his side of the story.
Manager Jim Jefferies confirmed that Nade would not be selected for the trip to Pittodrie as a result of the outstanding disciplinary proceedings following the incident after a defeat by Celtic earlier this month.
I've asked Laryea Kingston if he wants to stay and there's a possibility he'd love to stay
Hearts manager Jim Jefferies
"We've got to find out what happened from various people - myself included," he said.
"Then we'll sit down and look at it and then we'll call him to a meeting.
"It's only right that he's allowed his representation in that as well."
Jefferies this week began to process of drawing up a written code of conduct at Tynecastle, revealing he was not aware of any being in place before he succeeded Csaba Laszlo last month.
"I've been the one given the task to go away and put my thoughts to it," he said.
"I did that yesterday and I'll take it to our next meeting soon to see what people think of it.
"We'll try to implement it right away."
One player who has been disciplined by the club this season is Laryea Kingston, who fell out of favour under Laszlo.
Kingston, who made his first appearance for more than two months in Sunday's win over Hamilton, this week described Jefferies as a father figure.
The manager said of the Ghana midfielder, who is out of contract this summer: "I've asked him if he wants to stay and there's a possibility he'd love to stay."
