Stuart Hogg is one of six players added to the Scotland squad for their November internationals against Fiji, South Africa and Argentina.
Glasgow Warriors quartet Adam Ashe (back-row), Scott Cummings (lock), Nick Grigg (centre) and Hogg (full-back) are joined by inbound Premiership pair Josh Strauss (Sale Sharks back-row) and Duncan Weir (Worcester Warriors fly-half).
The additions follow injuries sustained by Scarlets back-row Blade Thomson (head) and Harlequins centre James Lang (rib) as they represented their club sides at the weekend, while David Denton (Leicester Tigers) and Matt Scott (Edinburgh) continue their ongoing recovery from head injuries with their respective clubs.
The national team also confirmed Edinburgh trio Ross Ford (hooker), Henry Pyrgos (scrum-half) and Dougie Fife (wing) have been released back to the club.
