The goalkeeper hasn't played since representing his country at Euro 2020 in the summer, with his last match coming in a 5-0 defeat to Spain in June, when he saved an Álvaro Morata penalty shortly before scoring a freak own goal.
But he returned to full training with Newcastle last month and has been selected by Štefan Tarkovic for World Cup qualifying matches against Slovenia, on Thursday, 11th November, and Malta three days later.
Meanwhile Ryan Fraser is once again in the Scotland squad for qualifiers against Moldova and Denmark.
The Tartan Army travel to Chisinau on Friday, 12th November, before hosting the Danes - who currently lead Group F, with Scotland in second place - at Hampden Park on Monday, 15th November.
