Experienced scrumhalf Greig Laidlaw returns to a 40-man Scotland squad announced for the Six Nations.
Laidlaw, 32, has not played a Test for almost a year and is just returning from a broken leg.
John Barclay retains the captain’s role he took on when Laidlaw was injured during last season’s Six Nations.
Uncapped props Murray McCallum and D’Arcy Rae are included, along with fullback Blair Kinghorn and scrumhalf Nathan Fowles.
Head coach Gregor Townsend also recalls Dave Denton, Scott Lawson, Gordon Reid and Jon Welsh after long absences from the international scene.
But there is no room for Josh Strauss, Matt Scott and Tim Visser, while John Hardie is overlooked as he nears the end of a 3-month “gross misconduct” ban.
Star fullback Stuart Hogg has not played since sustaining a hip injury during the warm-up for Scotland’s 53-24 win over Australia on 25 November 2017.
Lock Richie Gray has only just resumed action for Toulouse after recovering from a back problem, while Edinburgh centre Mark Bennett returns after missing the autumn series.
The campaign kicks off in Cardiff on 3 February and includes home games against France and defending champions England.
Last year, Scotland finished 4th, level on points with Ireland and France, after 3 victories, all of which came at Murrayfield.
Edinburgh prop Simon Berghan is suspended for the opening match and several frontrow regulars, including Ross Ford, Zander Fagerson, WP Nel and Allan Dell, are missing through injury.
Hooker Fraser Brown has been added to that list after suffering a series of head knocks this season, with 36-year-old Lawson back in the fold after winning the most recent of his 46 caps in 2014.
Laidlaw, who has captained Scotland on 31 occasions, missed the summer tour after being called up to the British and Irish Lions squad.
Townsend, who will be making his Six Nations coaching debut, has used Ali Price as his first-choice scrum-half in the absence of the former skipper, with Henry Pyrgos providing back-up.
With Berghan suspended and Fagerson and Nel sidelined, Newcastle’s Welsh is the leading contender to start at tighthead prop in Wales. The 31-year-old has not featured since the World Cup in 2015.
