The Principality Stadium roof will be open for today’s Wales-Scotland clash even though heavy rain is forecast for during the game.
That’s being done in order to try to reduce the spread of Covid-19 amid the 74,000 capacity crowd.
There have been numerous disputes over the roof in previous years with teams not agreeing over whether it should be open or shut.
But, on this occasion, the decision has been taken on health grounds.

Shutting the roof would effectively make the stadium an indoor venue and that has been ruled out, due to the pandemic.
So all three of Wales’ home Six Nations matches - against Scotland, France and Italy - will be staged with the retractable roof left open.
The Met Office forecast for today is for heavy rain from around about 2pm.
It is the first time fans have been able to attend a Six Nations matches in Cardiff for almost two years, with last season’s tournament taking place behind closed doors.
Supporters will have to show a Covid pass or proof of a negative lateral flow test to enter the stadium, with the WRU advising them to wear masks in the concourse areas.
Entry to the ground is being staggered, with fans able find their entry time and gate on their ticket.
New rules are also being trialled, with food and drink outlets on the concourses closing after half time, while lower-percentage beer will be made available.
That’s in response to anti-social behaviour reported during the autumn internationals.
The WRU say they will serve fans who have been waiting in queues, but stewards will be on hand to turn away latecomers who join the queue at the start of the second half.
Free water stations can be found throughout the stadium, while the WRU is emphasising responsible drinking, positive behaviour, consideration of others and fans taking responsibility for their own actions.
Stewards are also set to address poor behaviour “with increased vigour”, and will reserve the right to refuse service or entry to the ground to intoxicated fans.
