Scotland head coach Gregor Townsend has added Harlequins fly-half James Lang and Edinburgh utility back Darcy Graham in the squad for their autumn international campaign.
Lang has already played two Tests for the Dark Blues that came against Canada and Argentina during the summer series this year after making his professional rugby debut with Harlequins in 2016.
His inclusion comes after Glasgow's Sam Johnson sustained a knee injury during the recently concluded Pro14 encounter against Munster last weekend while Matt Scott is also recovering from a concussion.
Meanwhile, uncapped Graham has been a part of the training squad of Scotland and has played for the Scotland U20 and Sevens side in the past.
The 21-year-old made a switch to Edinburgh in February but a knee injury hampered his participation with the club but since then has been impressive for his side in the Pro14 and Champions Cup campaigns this season.
Meanwhile, the Scotland team management has confirmed that Magnus Bradbury, David Denton and Luke Crosbie will return to their respective clubs for further rehabilitation.
Scotland will face Wales, Fiji, South Africa and Argentina on 3rd, 10th, 17th and 24th November respectively in their end of the year series.
