Hawks, holders of both the Premier One trophy and the national cup, have been granted dispensation to call off the Old Anniesland match because three of their players have been called up by Glasgow for the Celtic League game against Neath Swansea Ospreys, also on Saturday. The trio required for duty with the professional team at Hughenden are hooker Fergus Thomson, flanker Steve Swindall, and full back Colin Shaw.
A club losing more than two players for duty with a professional team can apply to the SRU championship committee for permission to postpone a league match.
A new date for the Hawks v Boroughmuir match has yet to be arranged.
