Scotland manager George Burley has drafted Lee Miller and Scott Robertson into his squad to face Argentina after suffering a series of withdrawals.
Dundee United midfielder Robertson is uncapped, while Aberdeen forward Miller could make his second appearance after featuring in the Kirin Cup in May 2006.
James Morrison and Ross McCormack have both been added to the list of call-offs, with Morrison out with a knee injury and McCormack struggling with a hamstring strain.
They join Rangers striker Kenny Miller (calf), Sunderland goalkeeper Craig Gordon (ankle) and Manchester United midfielder Darren Fletcher (knee), who have all pulled out of Wednesday's friendly at Hampden.
