Prop Euan Murray has joined up with the Scotland squad ahead of Saturday's visit of France after missing the opening three RBS 6 Nations matches.
The 33-year-old had been in danger of missing the whole tournament after cutting his thumb while chopping wood at a barbecue with his Worcester team-mates.
The experienced tighthead was still battling back from a leg problem picked up in November, during which he won his 58th cap against Australia.
Edinburgh half-backs Sean Kennedy and Harry Leonard also trained with the squad on Monday.
Kennedy returned to the Edinburgh side just before the hour mark of their victory over Ospreys on Friday night.
The scrum-half had spent the previous month on loan at London Irish, who called him in as emergency cover, with Edinburgh using the deal to help the 22-year-old complete his return to full fitness and match sharpness following a knee injury.
Stand-off Leonard, who is 21, has made 36 appearances for Edinburgh and is a former Scotland Under-20 international.
Meanwhile, hooker Guilhem Guirado has been called up to the France squad after Dimitri Szarzewksi was ruled out with an ankle injury.
Guirado, 27, won the last of his 18 international caps in June last year during a test in New Zealand.
France will be without their two first-choice hookers as
Benjamin Kayser was already sidelined for six weeks when he picked up a knee problem last month.
