Boroughmuir will give tight-head prop Bryce Blair a first start as they bid to develop further Premiership rugby momentum away to Edinburgh Accies at Raeburn Place.
However, the hosts have suffered a blow with Scotland under-20 threequarter Sam Atkin moving south this week to begin studies and take up a place in the Worcester Warriors Academy.
Accies have still to finalise a line-up but Boroughmuir, who have Robin Hislop back from Edinburgh Rugby and starting on the bench, promote Jamie Swanson at blind side flanker after good performances at reserve level.
In the backs Harry Leonard, fresh from a summer spent in New Zealand on a Macphail Scholarship, returns at stand off which means a switch to centre for ex-Accie Stevie Wilson.
Heriot’s report a clean bill of health for their trip to Gala and the only change is at stand off where Cammy Ferguson returns after missing last weekend’s clash with Accies due to work commitments.
Also in the Premiership former champions Currie and Ayr meet at Malleny Park.
