Uncapped duo Fergus Burke and Jack Mann have been named in the Scotland squad for the Six Nations.
Gregor Townsend has handed both the Saracens fly-half and Glasgow back-row ace call-ups for this year's tournament.
New Zealand-born Burke qualifies for Scotland through his Glaswegian grandfather, he was also eligible to play for England.
The 25-year-old moved to Saracens in the summer to fill the void vacated by Owen Farrell's move to Racing 92.
There are returns for Edinburgh hooker Dave Cherry, included for the first time since the Rugby World Cup, and locks Jonny Gray - who sat out the autumn after his summer move from Exeter to Bordeaux.
The 30-year-old has been selected despite picking up an ankle injury while on club duty last month, which was initially expected to keep him out of the beginning of the championship.
Edinburgh lock Marshall Sykes is also in and could add to the one cap he earned in the autumn of 2021.
Among the 15 backs selected, Ben White retains his place despite limited game-time for Toulon but there is no place for Glasgow captain Kyle Steyn or experienced scrum-half Ali Price.
Sione Tuipulotu will continue as captain having taken on the role for the autumn series.
