Referees to 31 May
There are two matches likely to demand greater attention - the Super 14 Final, refereed by Jonathan Kaplan, and the opening match of the Lions' tour refereed by Marius Jonker. The two matches are not far from each other.
There are other matches of great importance as well, including Test matches. In France there are semifinals a promotion decider while in Italy there are two Finals. Europe generally shuts down now, except, of course, for the French who still have a Final to play after this.
