The Six Nations comes to a grandstand finish on Saturday with Wales chasing a Grand Slam and England and Ireland hoping to snatch the title from them.
Wales will wrap up the title and complete their first tournament clean sweep since 2012 if they beat Ireland.
But defeat in their 14:45 GMT match in Cardiff would open up the title race.
Barring an improbably emphatic Ireland victory, England would lift the title by beating Scotland but a Scottish win would see Ireland retain the trophy.
Wales are aiming to land their fourth Grand Slam of the Six Nations era, with two already won under coach Warren Gatland, who is leaving his post after this autumn’s World Cup.

Gatland’s side are also looking to extend their national record-breaking winning run to 14 successive Tests.
If they fail, both England and Ireland are poised to post impressive statistics of their own.
England can lift their third title in four Six Nations campaigns under Eddie Jones, while an Ireland success would be Joe Schmidt’s fourth in six years in his final year as their coach.
