Captain Jamie Ritchie leads his country in their Pool B clash with defending champions South Africa at Marseille’s Stade Vélodrome, the blindside flanker joined in the back row by openside Rory Darge and Jack Dempsey at number 8.

Richie Gray and Grant Gilchrist, both of whom will be appearing at a third Rugby World Cup, combine in the second row.

George Turner gets the nod at hooker, packing down with Pierre Schoeman (loosehead prop) and Zander Fagerson (tighthead).

In the back division, Finn Russell – also primed for a third such tournament – links up with scrum-half Ben White, with centres Sione Tuipulotu and Huw Jones continuing their partnership for the Springbok showdown.

Prolific wingers Duhan van der Merwe and Darcy Graham are joined in the back three by full back Blair Kinghorn.

Scotland’s forward replacements comprise hooker Dave Cherry, props Jamie Bhatti and WP Nel (the latter another set to appear at a trio of Rugby World Cups), as well as the versatile Scott Cummings and Matt Fagerson.

Scrum-half Ali Price, centre Cameron Redpath and full back Ollie Smith complete Townsend’s 23-player selection.

Injury update: Stuart McInally has travelled out to France as injury cover for Ewan Ashman, who is recovering from an injury picked up in training this week which ruled him out of the match against South Africa. McInally has not joined the 33-player squad.
