Celtic striker Leigh Griffiths has been called up to the Scotland squad for next month’s EURO 2016 qualifier against the Republic of Ireland.
The 24-year-old ex-Hibs man has four caps to his name.
Dundee goalkeeper Scott Bain has been handed his first call-up to Gordon Strachan's squad ahead of the 5 June friendly with Qatar and the Dublin tie with Martin O’Neill’s side eight days later.
The 24-year-old Dens Park stopper has been rewarded for his impressive displays for Paul Hartley's side this season.
Meanwhile, Dark Blues boss Strachan has recalled Charlie Mulgrew despite the Hoops utility man having missed the last five and a half months with hamstring trouble, while Stoke's Charlie Adam is also included.
Ireland sit two points behind Scotland in the Group D table after five games.
Mulgrew was a key asset when the Scots fought their way to a vital 1-0 win over O'Neill's side last November and Strachan is confident the 29-year-old will have worked off his rustiness by the time the return comes along next month.
"Scott's has been playing well this year and our goalkeeping coach Jim Stewart has been impressed"
Strachan said: "Charlie has been back in the Celtic side and they would not have put him in if he was not right.
"He was a huge asset for us when we played the Republic last time - and I mean huge.
"I thought he had a terrific game and just having Charlie in the squad makes us stronger. Not just in midfield but in other positions too."
The biggest challenge for Scotland ahead of their Aviva Stadium date will be maintaining fitness levels until the game comes around.
Seven members of the 26-man squad who will cross the Irish Sea - David Marshall, Christophe Berra, Craig Forsyth, Gordon Greer, Ikechi Anya, Matt Richie and Johnny Russell - have already been stood down by their clubs following the completion of the English Championship campaign.
Strachan admits he will have to change his usual training methods to accommodate those who have been left idle but he insists his men will be in prime condition by the time they take on the Irish.
"This Qatar game will be great for the likes of Charlie Mulgrew and lads like Matt Ritchie whose seasons finished at the start of May," he said. "It is imperative they get games.
"But our training will involve a lot of games. Usually it's about movement and shape but to bring the boys up to speed, there will be more contact training.
"I'm glad Qatar have agreed to play us because we need games at this time of the year for certain players.
"Charlie Mulgrew has been injured for five months but the enthusiasm and adrenaline keeps you going for the first month back and we're hoping that's the case with Charlie. But I think we'll need to top the lads' fitness up a bit while they are here.
"My initial thought was about having two squads - one meeting on June 2 and the other on June 8 and we'd all get together for the Republic game.
But I've asked the experienced ones and ones who are playing if they need time off and they said, 'No we're going to be here on June 2'. That's thrown me a bit because I thought we'd have 18 - instead we have 26 players."
Bain's call-up was required after Hull stopper Allan McGregor requested time off to address a long-standing injury, while strikers Stevie May, Jordan Rhodes and Ross McCormack have been left out.
That made space for Adam and Griffiths to rejoin the national team after lengthy spells in the wilderness, although Parkhead duo Stuart Armstrong and Gary Mackay-Steven were again overlooked.
But Strachan insists every member of this group should be prepared to participate fully.
He said: "Scott's has been playing well this year and our goalkeeping coach Jim Stewart has been impressed by him. He's a player not only for the future, but for now.
"I saw Charlie play recently. We all saw his wonder goal against Chelsea. But there's more to it than that.
"There's been a consistency to Charlie's performances and he has found a position at Stoke that suits him. It's been a good two months for Charlie, that's for sure.
"Leigh is also hitting form just at the right time. He'll be fresh because he didn't play too many games at the beginning of the season.
"If you remember back two years ago to when Barry Bannan was on holiday and we called him in. Then after watching him train we decided he had to go into the team that faced Croatia.
"So we set a precedent that day that you can win a place if you impress at training.
"Charlie and Leigh have been here before. If I felt they didn't have a chance of playing I would have brought in some younger guys to fill up those spaces."
