Edinburgh duo Dougie Fife and Ben Toolis have been added to Scotland's extended training squad for the Rugby World Cup.
The pair are injury replacements for Glasgow Warriors lock Tim Swinson and Saracens centre Duncan Taylor, both of whom require corrective surgery to ongoing ankle and shoulder complaints respectively.
Swinson and Taylor are expected to be unavailable for up to three months, which rules them out of the national team's four warm-up games ahead of the World Cup.
Fife, 24, who has scored 16 tries in 64 games for his club, earned three of his six Scotland caps in the 2015 Six Nations, scoring the only try in the team's 15-8 loss to France in Paris.
Toolis, 23, earned his first cap as a replacement in the same campaign after a breakthrough season for the capital club, starting 20 from 22 matches and scoring his first try in the side's European Challenge Cup semi-final win over Dragons.
