Steve Clarke is hopeful that Kieran Tierney should return for Scotland's clash against England on Friday.
The Arsenal star missed Scotland's 2-0 defeat against Czech Republic in their opening Group D clash with a slight injury.
Tierney absence was a devastating blow as the Muirhouse man plays an important role in Clarke's preferred five-man defence.
Scotland travel south on Friday to face the Auld Enemy at Wembley and although Clarke hopes Tierney will return, the 57-year-old urged fans not to raise expectations.

"I'm hopeful, I wouldn't get over-excited about it but I am hopeful," said Clarke. "He's been good and an integral part of how we've played recently.
"The boys who came in defended, by and large, well if you take out the set-play and the wonder strike from their striker.
"We defended reasonably well. We miss Kieran.
"It was a big effort today, different players available. I'll have a good think about it.
"We'll go back to base camp and lick our wounds for 24 hours then we'll be ready for the game on Friday."
