Midfielder Ross McCrorie has joined Aberdeen team-mate Andrew Considine and Hibernian right-back Paul McGinn in earning a first Scotland call-up.
The trio have been added to the squad for home Nations League games against Slovakia and the Czech Republic.
They join the group that beat Israel on penalties to secure a Euro 2020 play-off final in Serbia next month.
McCrorie's brother, Robby, and McGinn's sibling, John, were both in Steve Clarke's original squad.
McCrorie, who is on loan at Aberdeen from Rangers, steps up from his role as Scotland Under-21s captain to join the senior squad a day after scoring for the age group in their win over the Czech Republic.
"Ross played last night for the Under-21s but I'd already pre-empted that he would come through that game OK, which he did," said Clarke on Saturday.
"He's come to join the squad in a good place. He's a versatile player, has done very well for Aberdeen in central midfield and can also play centre-back and right-back, so gives us good cover."

McGinn's call up coincided with a new deal for the defender, taking his time at Easter Road up to summer 2022.
The 29-year-old, the older brother of Scotland and Aston Villa midfielder John, has played 17 times for Hibs since ending his second spell with Scottish Premiership rivals St Mirren in January.
Defender Considine wins his first call-up at the age of 33 having played more than 500 games for the Dons - his only club - and having been a regular starter for his club this season.
"Considine is 'Mr Steady'," said Clarke. "He's had a great career at Aberdeen, a one-club man which doesn't happen very often.
"In my time at Kilmarnock we had 10 games against Aberdeen and he was a seven out of 10 every game he plays. Although he hasn't been involved at international level before, he has the experience to handle the situation.
"Paul McGinn's is a position we're a bit light on numbers in. He has done the hard yards, came from Queen's Park and worked his way up. He is probably having the best season of his career so far at Hibs. I spoke to [manager] Jack Ross about him and he was very praiseworthy of Paul. He deserves his place in the squad."
Scotland head coach Clarke was deprived of six players for Thursday's match because of Covid-19 and injury. His side are top of Nations League Group B4, having drawn 1-1 at home to Israel last month before beating the Czechs 2-1 in Olomouc.
