Super Rugby starts. Chris Pollock of New Zealand blows the first whistle to start the first match of Week 1. And in Europe the Six Nations and the European Nations Cup are again in action. It is, you may say, a busy weekend.

There has been a change of referee for the Brumbies-Force match in Canberra. Garratt Williamson is injured and Bryce Lawrence has taken his place.

In Tokyo there is the Final of the To League.
