Aberdeen centre-back Michael Devlin has earned his first Scotland call-up after three defenders left the squad ahead of Sunday's friendly against Portugal.

Charlie Mulgrew, John Souttar and Kieran Tierney - the three players who started in central defence in Israel on Thursday - have dropped out along with winger Robert Snodgrass.

Celtic's Ryan Christie and Aberdeen winger Gary Mackay-Steven have also been called up for the Hampden encounter.

Tierney has been rested after playing his 22nd game of the season in Thursday's 2-1 Nations League defeat, while the other three withdrawals wee all due to injury.

Mulgrew went off at half-time in Haifa while Souttar was about to be substituted before he was sent off.

Manchester United midfielder Scott McTominay remains with Alex McLeish's squad despite missing Thursday's game with a minor knee injury.

Former Hamilton captain Devlin has made 11 appearances for Aberdeen this season after missing the entire 2017-18 campaign through injury. The 25-year-old could feature alongside Dons team-mate Scott McKenna in central defence. Celtic's Jack Hendry is the only other centre-back in the squad.

Christie has won three Scotland caps over the past year while 28-year-old Aberdeen winger Mackay-Steven made his only full international appearance to date almost five years ago, when he came on for the last six minutes of a goalless friendly against the United States.
