Scotland international Bruce Douglas has signed a new two-year deal with Border Reivers.
The 26-year-old prop will link up with fellow internationals Ross Ford and Gavin Kerr in the Netherdale front row next season.
Scotland back-row forward Kelly Brown has also signed a new two-year contract with the Border Reivers.
Douglas said: "Teaming up with Ross Ford and Gavin Kerr next season will give us a pretty impressive front row.
"I have spoken with Frank Hadden and I have decided that, in the build-up for the World Cup, it's best for me to play in Scotland due to the amount of preparation that will go into the squad that is ultimately selected, of which I hope to be a part."
Douglas joined the Reivers from Harlequins in 2002 and made his first Scotland appearance in the November Test against Romania that year, and now has 41 caps to his name.
England flanker James Haskell insists he will be pushing as hard as possible to be back from a toe injury in time to make his case for a spot in Eddie Jones' side looking to defend their RBS 6 Nations title next year.
