Manchester United midfielder Darren Fletcher will captain Scotland in tomorrow's friendly against South Africa - but James Morrison has been forced to withdraw from the squad.
West Brom midfielder Morrison was set to win his first cap at Pittodrie after switching allegiance from birth nation England.
But a hamstring injury has robbed the 21-year-old of the opportunity to make an early impression on national team coach Alex McLeish.
McLeish said: 'Unfortunately, Morrison is out with a hamstring injury.
'He felt it on Saturday with West Brom, but thought it was just fatigue.
'Sadly, he has gone home, but we will monitor James in the next few weeks and months ahead.
'He would have been on the pitch at some stage, maybe not starting, but he is a bright young player and we are looking forward to seeing him in action.'
Fletcher, 23, takes over the captaincy in the absence of Barry Ferguson, who has been rested this week.
McLeish added: 'Getting a leader from the midfield is ideal as far as I'm concerned.
'Craig Gordon was a contender, but I am not big on goalkeepers being captain.
'If you are in the middle of the pitch, you are aware of everything and everyone is aware of you.'
McLeish has named an attacking line-up featuring three forwards, Everton's James McFadden, Celtic's Kenny Miller and Birmingham's Garry O'Connor.
Fletcher will have Celtic's Scott Brown and Celtic's Gary Caldwell - ostensibly a defender - alongside him in midfield.
In defence, Sunderland centre-back Russell Anderson gets a chance to perform in front of a Pittodrie crowd again, having given up the Aberdeen captaincy to move to the Barclays Premier League this summer.
He is joined by Rangers' Alan Hutton, Celtic captain Stephen McManus and Derby's 22-year-old left-back Jay McEveley, who will make his Scotland debut.
Gordon, also now at Sunderland after leaving Hearts, starts in goal.
