Fit-again Richie Gray has been added to the Scotland squad for the remainder of the Six Nations.
The experienced second-row forward returns from a long-term injury to be named in Gregor Townsend's revised squad ahead of their final two fixtures against Ireland and Italy, with 10 players added in total.
Alex Dunbar, Zander Fagerson, Darryl Marfo and Fraser Brown – who all featured in last year's autumn internationals – are also recalled after injuries, while George Horne has been handed a first senior call-up.
It caps an impressive season for Horne, whose older brother Pete is already in the squad, having scored 10 tries in his first 14 appearances for Glasgow this season to force his way into Townsend's thinking.
Flanker John Hardie also returns to a 40-man squad following a three-month suspension earlier in the season by his club, Edinburgh, for alleged cocaine use.
Hardie returned to action against Leinster in February and has started the last two games to earn selection.
Byron McGuigan and Lee Jones return from hamstring and head injuries respectively to rejoin the group, while Magnus Bradbury has been recalled.
Scotland travel to Dublin this weekend looking to back up an impressive 25-13 win over England last time out before finishing their tournament in Rome a week later.
