Oli Kebble is one of three uncapped players named in the squad. The loosehead has been rewarded for his consistent form in a Warriors jersey, earning his first call up to the squad having qualified to play for Scotland through residency in the summer.
Richie Gray is the most experienced Glasgow player named in Townsend's squad, with the 31-year-old looking to add to his tally of 65 caps for his country, the last of which came in during the 2018 Six Nations.
The Rutherglen-born lock is joined in the engine room by club-mate Scott Cummings, who retains his place having featured in all four of Scotland's 2020 Guinness Six Nation matches.
Robert Harley's recent run of form in a Warriors jersey has seen the back-rower called into Townsend's squad and is joined in the backrow by Number 8 Matt Fagerson, who won his most recent cap for his country in Scotland's 0 - 17 victory over Italy in the 2020 Guinness Six Nations.
Fiji Head Coach Vern Cotter also named his squad for next month's Autumn Nations Cup. Two 'Weegies fae Fiji' have been named in the 31-man squad, with lock Leone Nakarawa and hooker Mesu Dolokoto both selected.
Argentina have also selected their squad for the 2020 Rugby Championship. Warrior No. 313 Enrique Pieretto has been named amongst the forwards for the teams upcoming matches against New Zealand, Australia and World Cup Winners South Africa.
