Andy Robinson has been hit with a Six Nations injury worry after Glasgow duo Ruaridh Jackson and Moray Low limped off at the weekend.
Fly-half Ruaridh Jackson pulled a hamstring during Glasgow's 16-14 loss to Scarlets on Saturday, while prop Moray Low left the field with a knee injury after scoring a try earlier in the game.
Jackson's boot is tipped as a potential successor to that of Chris Paterson, who retired from international rugby in December.
Scotland kick off their Six Nations campaign against England at Murrayfield on February 4.
