National coach Gregor Townsend is due to announce his selection at lunchtime.
Redpath is the son of former Scotland captain Bryan Redpath but looked to have been lost to Murrayfield.
He was involved with Scotland at age-grade level but was then snared by England and played for them at under-20 level.
Redpath junior was selected in Eddie Jones’ 34-man full England squad for the 2018 tour of South Africa but was unable to travel because of injury. He remains uncapped.
In an interview with The Scotsman last year, Bryan Redpath said of Cameron: “He knows my feelings. I’d want him to play for Scotland. And he’s not tied to anything yet so never say never, as they say. But, in the end, it will be his choice to make, not mine.”
Cameron Redpath was born in Narbonne when his father was playing in France and grew up in England. He was educated at Sedbergh School in Cumbria and played for Sale Sharks before moving to Bath.
Other contenders who could force their way into Townsend’s Scotland squad today include Newcastle back-rower Gary Graham and Glasgow’s Huw Jones, who has converted from centre to full-back.
