Lock For Scotland’s Six Nations match against Ireland in Dublin on Saturday, Scott Cummings and hooker Fraser Brown return from injury.
The Glasgow attackers have not competed in the tournament this season.
Their inclusions come as little surprise, but Gregor Townsend has also called up Murphy Walker and Jordan Edmunds, two uncapped players.
Walker, a tighthead prop with Glasgow, is 22 years old, while Edmunds, a 25-year-old winger from Edinburgh, is a fixture in the Scotland Sevens squad.
After two wins and two losses, Scotland is in fourth place, while Ireland is in second place, two points behind France.
