Champions Glasgow Hawks are likely to be without Ian Kennedy, who is ill, for the clash with Stewart's-Melville at Old Annielsand. Ally Maclay will move to centre with Steve Gordon on the wing. Richie McKnight resumes at scrum-half, and with Nick Cox and Peter Dalton injured Gordon McFadyen gets his first start since returning to the club.
The Colleges include former Scotland caps, Craig Joiner and Graham Shiel.
The very week during which Eddie McLaughlin found himself on the Glasgow Warriors bench for the first time is the very time he has been told by the pro district that his short-term contract is not being renewed. That may have come as a bit of a shock, but while the Australian was in attendance at Hughenden last night, he will this afternoon turn out for Ayr, who have taken over his contract.
