Andy Lloyd has been drafted into the starting XV for Friday's Magners League game against Glasgow at Firhill
Lloyd gets the nod in place of Jonathan Thomas, who didn't travel with the team on Thursday afternoon.
Scott Johnson explained:
"Jonathan's had a long time on the sidelines and has just been feeling a bit sore after two hard games. It's important that we manage a player's return to action properly. With a long season ahead and some big games coming up we considered his position and just felt that he was best off staying behind to do some conditioning work and to prepare for next weekend properly."
