Scotland suffered a fresh injury blow on Friday when it was announced that No 8 Josh Strauss will miss the rest of the Six Nations with a kidney injury.
The news that Strauss had been sidelined came just two days after it was confirmed that Greig Laidlaw's ankle injury had ruled the Scotland captain out of the remainder of the tournament.
Both players sustained their injuries during Scotland's 22-16 loss to France in Paris last Sunday, with Strauss completing the game after Laidlaw went off in the first half at the Stade de France.
A statement issued by the Scottish Rugby Union (SRU) said South Africa-born Strauss, 30, had suffered a "blow to his flank" in what was his 11th Test appearance.
The SRU added: "After completing the match, he was scanned in Paris. Both the scan, and the player, were reviewed at Spire Murrayfield Hospital back in Scotland, where the full extent of the injury was confirmed.
"Strauss will now return to his club Glasgow Warriors for further care and a review of the injury will be scheduled in approximately six weeks' time."
Scotland continue their Six Nations campaign when they welcome Wales to Murrayfield a week on Saturday.
