It's the penultimate round in the BT Premiership, and Ayr travel to Old Anniesland to take on Glasgow Hawks on Saturday, kicking off at 3pm.
The home team have been chasing the visitors up through the table for much of the season, and with just a handful of points between the two, tomorrow's game will be an important one for both in terms of securing home semi-final play-offs.
Ayr head coach Calum Forrester is looking forward to the trip to the west end of Glasgow.
"It's set to be an exciting weekend in the BT Premiership, with the result of every game having a meaningful outcome on league positions. Hawks are the highest points scorers this season, so our defence will need to be at its best."
Several experienced players, such as David Armstrong, Craig Gossman and Will Bordill, return to the starting line-up. Glasgow Warriors have released former Millbrae man James Malcolm for the day and he forms a formidable front row alongside George Hunter and Steven Longwell.
15. Grant Anderson; 14. Danny McCluskey, 13. Archie Russell, 12. Ross Curle, 11. Craig Gossman; 10. Frazier Climo, 9. David Armstrong; 1. George Hunter, 2. James Malcolm, 3. Steven Longwell; 4. Robert McAlpine, 5. Scott Sutherland; 6. Blair Macpherson, 7. Will Bordill, 8. Pete McCallum (c).
