Referees to 27 December
It's Christmas time with all its good cheer. It's cold in Europe but, despite the good cheer and the freezing weather, some rugby will try to be played, and so there will be referees out there in their thermals, careful of the danger of excesses.
There will be no club rugby in Scotland, Ireland, France and Italy, which may make life easier for some.
