Referees to 18 March
It's yet another big action weekend for players and referees as the Six Nations comes to an end and the Super 14 rackets on.
Will St Patrick's Day increase the legendary luck of the Irish? They stand to win two championships this weekend.
Their senior team could win the Six Nations, provided of course that they win and score more points than France already have.
Their Under-20 team is the only unbeaten team in the Under-21 Six Nations and stands to win a Grand Slam.
England's women look likely to win a Grand Slam in the Women's Six Nations.
In the final round of the Women's Six Nations all the referees are women.
Dean Richards will be off to Madrid for an ENC Test when the struggling Spaniards play the ambitious Lelos. It is just his second Test and we wish him well.
James Jones will be off to Czech Republic for his very first Test when the Czechs play the Oaks. We wish him well.
