The Six Nations title decider between Wales and England will be played beneath a closed roof at the Millennium Stadium, the Welsh Rugby Union confirmed on Friday.
"The WRU can confirm the roof at the Millennium Stadium will be closed for tomorrow's Wales v England RBS 6 Nations fixture," read a statement from the organisation.
With heavy rain forecast on Friday and showers due on Saturday evening, both teams have agreed to play the match with the roof closed.
The two sides played beneath a closed roof when they last met at the Millennium Stadium in 2011, with England prevailing 26-19.
England will claim their first Grand Slam in a decade if they win in Cardiff on Saturday, but Wales can take the championship if they win by eight points or more.
A seven-point victory margin will also give Wales the title, provided they preserve their advantage over England in the number of tries scored across the tournament.
