Scotland were tonight hit by three more injury withdrawals for Wednesday night's friendly against Argentina.
Manchester United midfielder Darren Fletcher was yesterday ruled out with a knee problem and PA Sport understands he has been joined by strikers Kenny Miller (Rangers) and Steven Fletcher (Hibernian) and Sunderland goalkeeper Craig Gordon.
There are also concerns over West Brom midfielder James Morrison and Cardiff striker Ross McCormack.
The precise details of the injuries to Miller and Steven Fletcher are unknown, though both completed a full 90 minutes for their clubs yesterday.
Miller, 28, also withdrew from the squad for last month's World Cup stalemate against Norway, citing a niggling hamstring strain which has dogged him since September's qualifier in Macedonia.
Gordon, who has been manager George Burley's first-choice since he took charge at the start of the year, has not played for his club for almost a month due to a chipped ankle bone.
Morrison limped out of West Brom's 3-0 Barclays Premier League defeat to Chelsea on Saturday with a knee injury shortly before the hour mark.
McCormack has been out of action for Cardiff for a fortnight after suffering a hamstring problem in a Coca-Cola Championship defeat to Wolves.
He had been expected to return for yesterday's match against Crystal Palace but aggravated the injury in training and did not feature.
