The team sees Fergus Thomson, Gregor Hayter, Colin Gregor, Andy Craig and Mike Roberts all starting while Rory Lamont moves to fullback. Campbell said: "It's good to give these guys, some of whom are returning back from injury, a run as they're needing match time to return back to full fitness and for that it's essential for them to get games."
In addition to those in the starting line-up, Scott Barrow is named in the 22 for the first time since his recent groin operation.
