Ireland host Scotland in their Six Nations Super Saturday finale hoping they can do enough to win the title. Andy Farrell's men are reliant on England doing them a favour against Grand Slam-chasing France later in the evening.
The Triple Crown is also on the cards, with Ireland not having won it since their own Grand Slam in 2018.
As for Scotland, they have endured an up-and-down campaign but, like Wales, will be trying to finish the tournament in third place in the table. Scotland haven't won in Dublin since 2010, though, and they have only won three of the last 14 meetings with the Irish.

What's the Ireland v Scotland team news?
Iain Henderson, Jack Conan and Mack Hansen have been restored to Ireland's starting XV for Saturday's Guinness Six Nations clash with Scotland in Dublin. Lock Henderson takes the place of head injury victim James Ryan, while Conan is preferred to Peter O'Mahony in the back row and Hansen comes in for Andrew Conway on the right wing.
Ulster captain Henderson, who has been handed his first start of this year's championship, played 78 minutes of last weekend's 32-15 win over 14-man England after vice-captain Ryan was forced off by the challenge which led to Charlie Ewels' early red card.
With Ryan unavailable due to concussion protocols, Kieran Treadwell - who was on the scoresheet in the round-three win over Italy - will provide second-row cover from the bench.
Conan regains a starting role following two games as a replacement on the back of his try-scoring cameo helping the Irish to victory at Twickenham. He will begin at number eight, pushing Caelan Doris to blindside flanker, with O'Mahony dropping to the bench. Australia-born Hansen was not involved in London but has been brought back in the other change to Andy Farrell's starting line-up as Conway has a knee niggle.
Scotland, meanwhile, have made two changes to the line-up which beat Italy. Finn Russell is named on the bench as Blair Kinghorn gets his first start of the Championship at fly-half. Jonny Gray returns to the second row, coming in for his Exeter Chiefs teammate Sam Skinner.

What have the coaches said?
Ireland head coach Andy Farrell : "The ideal part for everyone starting the competition, they all want to go for a Grand Slam, there’s no doubt about that. “There’s only one team that’s allowed to do that, but we’re on to the next task and the next task for us is making sure that we prepare unbelievably well for what is a massive occasion for us at Aviva Stadium, playing for a trophy. Playing for the Triple Crown is huge for us and performing and putting pressure on France is what we’re about, but at the same time we know that Scotland will want to finish the competition off really well."
Scotland head coach Gregor Townsend: "They play ambitious rugby, allied to a very good detail around the set-piece, the contact. They’ve got some very good individuals and they’re full of confidence. We’ve got to put them under pressure, we’ve got to take the game to them and we’ve got to deliver our best performance of the season to come away with the victory."
