Rangers goalkeeper Allan McGregor has withdrawn from the Scotland squad due to face South Africa on Wednesday.
McGregor is carrying a minor ankle injury and it has been decided he will not be risked in the friendly meeting at Pittodrie.
The 25-year-old sustained the injury in Rangers' 7-2 victory over Falkirk on Saturday and the shot-stopper will now fly back to Glasgow.
Scotland manager Alex McLeish, who already has goalkeeping cover in Craig Gordon, Neil Alexander and David Marshall, will not call-up a replacement.
McGregor currently has one international cap to his name, but he is a regular in the Rangers first-team.
