Thom Evans is on the wing with Kelly Brown starting in the pack. Ed Kalman - who was listed to play for Ayr in the British & Irish Cup - and Colin Gregor are among the replacements.
The major surprise in the line-up is Hugo Southwell's appearance at stand-off. Southwell has spent the majority of his playing career operating in the full-back role.
