The Southampton striker – who previously turned down Scotland in 2017 when he was a 20-year-old at Birmingham City – has been persuaded into committing his international future to the nation he qualifies for through a maternal grandparent.
The 24-year-old bolsters the options in the attacking corps, where he is joined by Hibs striker Kevin Nisbet. The summer signing from Dunfermline has bagged 14 goals in his first season at Easter Road and was the subject of a £3 million bid from Birmingham City in the January window.
Dundee United striker Lawrence Shankland and Sheffield United attacker Oliver Burke drop out of the unit as a result.
There’s also a place in the squad for Celtic outcast Jack Hendry. The centre-back is on loan at Oostende, where he has sparkled in the top-tier of Belgian football this campaign. The 25-year-old previously made three appearances under former boss Alex McLeish but hasn’t featured since 2018.
There is no place, however, for in-form Celtic midfielder David Turnbull. The youngster has netted eight times in 32 appearances this season and had been fancied for a call-up. Team-mates Callum McGregor, Ryan Christie and Greg Taylor are once again included.
Ryan Jack and Jon McLaughlin make up the representatives from Rangers, while Hearts goalkeeper Craig Gordon retains his place in the squad.
Scotland get their World Cup qualification campaign underway with a home clash against Austria on March 25. They’ll then travel to Israel before returning to Hampden Park to host the Faroe Islands.
