Three Irish players have lodged filings against the IRFU and World Rugby. The firm representing them has previously said it is handling a number of rugby concussion cases and is working closely with the UK firm which earlier this year issued proceedings in a class action against World Rugby.

A series victory in New Zealand is an extraordinary achievement in its own right but there is another prize at stake and now is the time for Andy Farrell to experiment.

Leinster's growth was once watched over by a protective IRFU but they saw the need for independent thinking and since then, the development has been spectacular.

The lazy view is that collisions, and therefore head collisions, are such a fundamental part of rugby that they can't ever be fully removed from the game. Players know the risks, this argument goes. But they don't because we still don't know enough about concussion.

The critic's of Ireland's performance at Twickenham are ignoring how hard it can be to play against 14 men but Andy Farrell's side still didn't learn lessons from the Italy game.

Ireland's triumph over the All Blacks was based on a more expansive style of play but at its heart it was an ability to stay calm which can be truly encouraging as Andy Farrell's side face even bigger challenges over the next two years.

Ireland's performance against Japan was radically different to the first two years under Andy Farrell and the Joe Schmidt era but at this delicate stage of development, a heavy defeat against New Zealand would be a killer blow.

The All Blacks coach Ian Foster has his detractors. They have been silenced by his team's performances in recent months but the big tests are to come, their former coach Steve Hansen tells New Zealand journalist Robert van Royen.

Ireland aren't bad enough to give out about or good enough to get excited about so where does Andy Farrell go from here?

Gary Keegan has been involved in many of the most important developments in Irish sport. As a Dublin footballer, Paul Flynn worked with Keegan and in this conversation they discuss leadership, living in the present and Jim Gavin's endless curiosity.
