Dunfermline Athletic have suffered a double blow after Gary Mason lost his appeal against a red card and Jason Thomson suffered a groin injury.
Mason was sent off for serious foul play by referee Stevie O'Reilly following a challenge on Johnny Russell in the 4-1 defeat by Dundee United.
The midfielder has received a two-match suspension.
And on-loan Hearts defender Thomson will have a scan after damaging his groin in training.
Dunfermline have already suffered a string of injuries and have now lost two more ahead of Saturday's visit to Edinburgh to face Hibernian.
Pars manager Jim McIntyre told his club website: "We've lost another one this week in Jason Thomson, who has done his groin in training, and to lose another player to suspension is really disappointing."
Joe Cardle and Martin Hardie are back in training following injury, although only the former has a chance of facing Hibs, while Liam Buchanan has recovered from illness.
McIntyre had argued that Mason slid along the ground and won the ball, but their case was thrown out by the Scottish Football Association's fast-track tribunal at Hampden Park.
"Unfortunately they ruled against it and he has been given a two-match ban," he said.
"They thought it was a lunge, we didn't and that's why we appealed, but the appeal backed the referee on this occasion and we move on. It's done and dusted."
