 This was introduced in 1973 and still flourishes today with several of the country's original clubs still very much in evidence, such as Heriots, West of Scotland, Watsonians and the famous 'border' clubs such as Gala, Hawick, Jed-Forest, Kelso and Melrose.However the advent of professionalism saw Scotland's District championship abandoned and two (later three) 'Super Districts' formed, which have resulted in the top players generally being unavailable for their clubs.These teams play in international club competitions such as the Heineken Cup and the Celtic League.
