Ireland's request granted as Wales forced to keep Principality Stadium roof open

The Principality Stadium roof will be open for Saturday's mouth-watering Six Nations clash between Wales and Ireland.

Despite the awful weather conditions forecast for this weekend,Ireland have insisted the roof remain open, informing Wales of their decision yesterday afternoon.

Wales sought to close it, citing weather concerns, but both teams must agree on the decision or - under Six Nations regulations - it stays open.

In 2007, the roof was closed, on Irelands request, but Wales put the sprinklers in half an hour before kick-off as Ireland lost their footing on their way to a 22-9 defeat.

For us, I think, the last time it was closed," Ireland head coach Joe Schmidt said in his pre-match press conference.

"We arrived there and there was a lot said about making it good for spectators and the sprinklers were on for 30 minutes and the ground was very damp before the game started.

That probably enters into our mind: which closed is it going to be? Closed and wet or closed and dry? If it closed and wet you might as well have the window open and let the rain come in.

The Principality Stadium roof will be open tomorrow for Wales' #SixNations Grand Slam decider against Ireland - at the request of the Irish.

Schmidt continued: For us, last time we said we dont mind you choose. They chose to close it but made the field incredibly wet at the start of the game. We would probably be happy enough if it was open anyway. Well adapt to whatever conditions the game is played in.

If the Six Nations decide it is going to be closed we will play in those conditions, if open we will play in those conditions.

Unbeaten Wales can win the Six Nations title and claim a first Grand Slam since 2012 if they overcome Ireland, who will retain their title if they win and Scotland beat England later.

Lock Tadhg Beirne will make his Six Nations debut, while Rob Kearney and Sean O'Brien both return to the side.
