Charlie Adam has withdrawn from Scotland's squad to face Estonia in their Euro 2012 qualifier in Tallinn on Tuesday.
The midfielder came off towards the end of Saturday's 2-2 draw against the Czech Republic with a hip injury.
The Liverpool man's ommission comes as striker Craig Mackail-Smith pulled out with a back injury, while Scott Brown and Kenny Miller will miss the match through suspension.
Craig Levein's side currently sit third in Group I, five points off the second-placed Czechs and 10 points back from leaders Spain.
