There are also semifinals in England – the Premiership.
In France, Brive have been relegated to Pro D2 and, after beating Oyonnax who are also relegated, Grenoble have been promoted to Top 14 for next season. Perpignan are also promoted. This weekend there are two Top 14 playoffs . Montpellier and Racing are already confirmed as semi-finalists.
