In an entirely fresh pack, Gilchrist will link up in the second row with Sam Skinner, who was a replacement in that Tonga victory.

The back row sees the first appearances of the tournament for openside flanker Hamish Watson – named as a vice-captain – and blindside Luke Crosbie, with Matt Fagerson restored to the starting XV at number 8.

A freshened front row will bring about a Rugby World Cup debut for tighthead prop Javan Sebastian, who is joined by loosehead Jamie Bhatti and Ewan Ashman at hooker.

In the back division, Chris Harris, also a vice-captain, is partnered at centre by Cameron Redpath.

Ben Healy is named at stand-off for a first tournament showing, with the experienced Ali Price selected at scrum-half.

Kyle Steyn retains his place in the back three, switching wings to accommodate the return of Darcy Graham, with Ollie Smith operating at full-back.

Among the replacements, hooker Johnny Matthews is in line to make his Scotland debut having been called into the squad earlier in the week to replace the unfortunate Stuart McInally.

The remaining substitutes were all involved against Tonga, with Matthews’ front row colleagues Rory Sutherland and WP Nel, as well as Scott Cummings and Rory Darge, completing Scotland’s forward options from the bench.

George Horne and Blair Kinghorn, both try scorers last time out, are joined by Huw Jones in rounding off the matchday 23.
