Ayr have their first of two back-to-back away games on Saturday as they travel to Edinburgh to play Watsonians at Myreside in the BT Premiership.
The men in pink and black climbed back to the top of the table after last week's win against Glasgow Hawks, but they will be on their guard against ambitious Watsonians, who had a great start to their league campaign and will be eager to perform well in front of their home fans after some disappointing results of late.
Ayr head coach Calum Forrester has his team ready for the visit east.
"Last week the pack put in a really dominant performance and we will be looking for them to back it up this week in what will be a tough trip to Myreside."
There are a few changes to the squad, with Danny McCluskey taking over from the injured Ross Curle at stand-off; Robbie Smith starts at hooker after impressing from the bench in his first senior season; and Ruaridh Mackenzie moves into the starting XV following his try-scoring debut last week.
George Hunter stays in the back row for the third week, and Glasgow Warriors' Canadian international prop Djustice Sears-Duru retains his place in the front row.
Club captain Pete McCallum is amongst the substitutes and will hopefully make his return to action after overcoming a knee injury.
