Hull City attacker Shaun Maloney has been recalled to the Scotland squad for the forthcoming World Cup qualifying fixtures against Lithuania and Slovakia.
Maloney, 33, was left out of this month's 5-1 victory over Malta, but returns along with Lee Wallace and Kieran Tierney, who have both recovered from injury.
Celtic striker Leigh Griffiths is also back in the fold following a hamstring problem, as Scotland look to maintain their winning start to Group F.
Manager Gordon Strachan said: "Shaun has been used as a substitute quite a lot with Hull and played a game last week against Stoke, a terrific game. So he is back in again.
"He has professionalism, ability, intellect, willingness to play for Scotland. So he's got all these traits that we want along here.
"And we still have some of the younger lads in the squad as well. If they are good enough we'll stick them in, we will bypass the U19s and 21s which we did with Ollie [Burke]."
Scotland host Lithuania on October 8 before travelling to Slovakia three days later.
