Che Adams is out of Scotland's World Cup qualifier with the Faroe Islands after the striker suffered a muscle injury in Saturday’s win over Israel.
Adams will not travel for the trip to Torshavn, instead returning down south for treatment and to be assessed by Southampton.
Saints don’t want to take any risks as they take on Leeds United at the weekend.
Steve Clarke does however have another key man he can count on at the other end of the park as Grant Hanley returns from suspension.
A win against the Nordic minnows is vital if Clarke's men are to solidify their second-placed position in Group F.
That would leave them just one more success against Moldova away from sealing a play-off spot to reach the 2022 World Cup.
Ryan Christie, who replaced Adams against Willi Ruttensteiner's side, is a likely candidate to replace him.
Kevin Nisbet of Hibs could also come in after he started in the home win over Moldova last month while Ryan Fraser is another option.
