The second fallow week is behind us, and we're officially into the business end of the 2023 Guinness Six Nations.
Through three games, Ireland are very much in control of their own destiny. Two wins from their final two games against Scotland and England will see Andy Farrell's side claim just a fourth Grand Slam in their history.
They could even head into Sunday's game with the possibility of securing the title with a game to spare.
If the winner of Saturday's meeting between England and France do so without a try-scoring bonus-point, then Ireland's lead would become insurmountable if they beat Scotland and score four or more tries in the process.
Talk of winning a championship is getting ahead of ourselves though, because a win of any kind will be more than acceptable against a Scottish team who are making real strides in the last 12 months.
Gregor Townsend's side are still in the mix for the title, and if they can turn Ireland over on Sunday, they'll be in with a real shot of winning the championship when they host Italy in Round 5.
Scotland are also playing for a Triple Crown this Sunday, having beaten England and Wales earlier in the championship, and while the overall title is the one they want to get their hands on, the prospect of a first Triple Crown success since 1999 will make for a ferocious atmosphere at Murrayfield.

WEATHER
It's expected to be tough day for rugby in Edinburgh on Sunday, with temperatures of around 6C, and rain forecast throughout the afternoon.
While Ireland have won the last seven meetings in a row between the sides, their last three visits to Murrayfield have been far from straightforward.
In 2021 they needed a Johnny Sexton penalty in the 77th minute to secure a 27-24 win, in 2019 they ground out a nine-point victory, while in 2017 they were beaten 27-22, Scotland denying an Irish comeback with two late Greig Laidlaw penalties.
Crucially though, both of Ireland's Six Nations defeats in Edinburgh in the last decade have come without Johnny Sexton. The Ireland captain has enjoyed a great record in this fixture down the years, winning in 12 of his 14 meetings with the Scots, and his only Murrayfield defeat coming in a World Cup warm-up game back in 2011.
He could even make some personal history in Edinburgh, needing just eight more points to edge past Ronan O'Gara (557) as the Six Nations record points scorer.
The out-half is restored to the starting lineup for Sunday's game, having missed the win in Rome a fortnight ago, as is Garry Ringrose, who has recovered from a calf injury, while Tadhg Furlong comes in to make his first appearance since December.
Head coach Andy Farrell is taking no chances with his team selection, and aside from the injured Tadhg Beirne, it looks like his strongest possible selection. Conor Murray gets back into the starting side, having made a big impression off the bench in Rome, while Peter O'Mahony comes into the back row, allowing Caelan Doris (below) shift across to number 8. Dan Sheehan, meanwhile, gets the nod over Rónan Kelleher to start at hooker.
Scotland make two changes from their defeat in Paris, with one of those enforced; Jonny Gray coming into the second row to partner his older brother Ritchie, after suspension ruled out Grant Gilchrist.
The other change also comes in the pack, former Australia international Jack Dempsey makes his first start of the championship, replacing Hamish Watson in the back row.
Sunday will be a big day for full-back Stuart Hogg, the Exeter Chief making his 100th appearance for his country, becoming just the fourth men's player to reach that milestone for Scotland.
While he hasn't scored yet in the championship, Hogg has played his part in what's been an exciting an exciting Scottish backline, who have contributed 10 of their side's 12 tries, with Huw Jones, Duhan van der Merwe and Kyle Steyn sharing seven of them.
Scotland: Stuart Hogg; Kyle Steyn, Huw Jones, Sione Tuipulotu, Duhan van der Merwe; Finn Russell, Ben White; Pierre Schoeman, George Turner, Zander Fagerson; Richie Gray, Jonny Gray; Matt Fagerson, Jamie Ritchie (capt), Jack Dempsey
Replacements: Fraser Brown, Jamie Bhatti, Simon Berghan, Scott Cummings, Hamish Watson, Ali Price, Blair Kinghorn, Chris Harris
Ireland: Hugo Keenan; Mack Hansen, Garry Ringrose, Bundee Aki, James Lowe; Johnny Sexton (capt), Conor Murray; Andrew Porter, Dan Sheehan, Tadhg Furlong; Iain Henderson, James Ryan, Peter O'Mahony, Josh van der Flier, Caelan Doris.
Replacements: Ronan Kelleher, Cian Healy, Tom O’Toole, Ryan Baird, Jack Conan, Jamison Gibson-Park, Ross Byrne, Robbie Henshaw.

Gregor Townsend (Scotland head coach): "It's the best Ireland team we’ve faced. They’re on the back of a lot of big wins and they’ve got their strongest team they could probably put out to play us this weekend, so - while we’ve improved - we’ve got more improvement in us and we’re going up against a team that’s on top of their game."
Andy Farrell: (Ireland head coach): "Anyone who watches the Scottish game at this moment in time, they realise they play with pace onto the ball, they've got a nice flow into how they galvanise the backline together the whole time. The forwards are pretty physical, the breakdown’s always very contested. So, yeah, they’re in good form."
Scotland v Ireland is the final game of Round 4, with the weekend's two other games taking place on Saturday.
First up on Saturday, Italy will hope to make it consecutive wins against they meet Wales in Rome at 2.15pm, while at 4.45pm England host France at Twickenham, with Fabien Galthie's side looking for a first Six Nations win in London since 2005.
