STEVE CLARKE tonight revealed David Turnbull will return to Celtic from Scotland duty over an ankle injury.
The Scotland boss admitted Turnbull won't feature in the international break as a knock picked up in action against St Mirren.
Turnbull started in Celtic's 2-0 loss to St Mirren on Saturday but according to Clarke suffered an injury in the match.
It was hoped the midfielder would recover to be able to feature for Scotland, but he's now withdrawn from the camp and returned to Celtic.
Clarke confirmed the news after the 3-0 win over Ukraine as he admitted he could call-up two more players with Turnbull out and Nathan Patterson stretchered off at Hampden.
He said: "We'll go away and we'll have a little chat about it.
"David Turnbull pulled out the squad, he picked up an ankle knock at the weekend that we thought would clear up.
"It's not going to clear up in time for us so he's better to go back to his club and get ready for their next game.
"I'll probably need to call up at least one, maybe two players."
