He was still feeling the problem today and, in light of the game’s friendly status, manager George Burley has decided it would be unwise to take any risks with him.

And, with skipper Barry Ferguson only expected to get a half because of his well-documented ankle trouble, that points to Dundee United midfielder Robertson being involved at some stage.

Robson’s absence brings the total number of call-offs to seven, a problem which was also evident in Burley’s previous six games as Scotland boss.

Goalkeeper Craig Gordon, Kenny Miller, Darren Fletcher, Steven Fletcher, James Morrison and Ross McCormack have also been forced to withdraw.

Only Robertson and Aberdeen’s Lee Miller were called up as replacements, leaving selection options limited.

Meanwhile, boss Burley spoke of his admiration for new Argentina coach Diego Maradona.

He said, “Maradona is the best player I have ever played against and anyone who was involved in 1979 when he played against Scotland in a friendly at Hampden would agree with that.

“In my opinion, he was only behind Pele as the best-ever player. He was a magnificent footballer.”
