Scotland have lost Rory Sutherland and Rory Darge to injury ahead of their clash with Australia on Sunday.
Uncapped Glasgow flanker Darge did not feature in Scotland’s emphatic win over Tonga on Saturday while British and Irish Lions prop Sutherland was absent as Worcester beat Sale.
Edinburgh forward Magnus Bradbury, a late call-up to the squad last week, and winger Damien Hoyland, have also dropped out after not featuring against Tonga.
Three uncapped props – Northampton’s Nick Auterac, Javan Sebastian of Scarlets and versatile Wasps forward Robin Hislop – have been added to the squad.
They had all been called up to Scotland’s squad for the ill-fated summer tour which saw all three games cancelled.
Glasgow lock Scott Cummings also comes in but is unavailable for selection following surgery on a hand injury last month.
