We’ll get back to the build-up to today’s game in a bit, but first an important topic again in the news this week – the complex concussion question continues to trouble rugby:

Need a reminder of all of the Six Nations action so far and the fixtures still to come in the championship? We’ve got you covered:

Kyle Steyn reckons Scotland and France are ready to put on a show in today’s high-stakes Six Nations clash at Murrayfield.

The Scots could leapfrog their visitors to go top of the table with a bonus-point victory while Les Bleus will secure the title with a game to spare if they notch a bonus-point win in Edinburgh.

Steyn acknowledged “it is huge and we haven’t shied away from that”. And the Glasgow wing feels this showdown carries additional excitement because both sides are intent on playing swashbuckling running rugby.

“We know the challenge that’s coming this week and the kind of machine that is French rugby at the moment,” said Steyn.

“Whenever we’ve come up against these guys, we’ve had some really good games, some really fun clashes, some really big clashes, so I’m just looking forward to another one of them.

“It’s two teams that love to play rugby. They are often really fatiguing games because you’ve got two teams that are trying to have a crack. Both teams will make errors and we obviously know how lethal they are from transition, so you’ve got to try not to make those errors.

“At the same time, they’ve got a big juggernaut up front that needs to move and we’re relishing the chance to have a go against them and try and make them defend. You look forward to these games, they’re always so much fun.

“Test matches can be so different. When you play an Ireland or other teams like that, it just seems like a gridlock game the whole week. But this is a game where you just know it’s going to be fun from one to 80. You don’t know what’s going to happen, but it’s going to flow and it’s going to be a lot of fun.”

There was a slightly bizarre back-and-forth between Fabien Galthie and Gregor Townsend this week, with the French head coach criticising the size of the Murrayfield away changing room in his pre-match press conference, and Townsend leaping to the defence of the grand old ground and offering a dig at the size of the French staff.

“The changing room, it is worth you knowing that it is, for me, the smallest in the world,” Galthié said. “It forces us to change in the corridors for an international match. We need to say it as it is.

“We have regularly asked if they could give us the room next door, which is available and is the other part of the dressing room, but we don’t have it. Therefore, we will continue to prepare and get changed in the corridor for a Test match.

“The referees’ dressing room is bigger than ours. It is just next to ours and it is bigger. Anyway, it sets the tone, we know what we’re getting into as soon as we arrive at the stadium.”

Townsend, meanwhile, responded: ““I think it’s the first time the opposition have complained about our away changing room publicly,” Townsend countered.

“It’s obviously the changing room Edinburgh use week in, week out. It’s a changing room every away team have used over the last 20 years. France have got a huge staff, which I think is part of the issue. But it’s not really my job.”

All good fun – I think…

Sione Tuipulotu has challenged Scotland to take their Six Nations title bid to the final weekend by ensuring maximum discomfort for France at Murrayfield.

The Scots, chasing a first top-two finish in the championship this century, would leapfrog their visitors into first place if they pull off a bonus-point win and deny Les Bleus a losing bonus point.

Similarly, a France bonus-point victory in Edinburgh would secure a second consecutive title for Fabien Galthie’s men.

Scotland skipper Tuipulotu admitted the top-of-the-table showdown on the penultimate weekend of the championship counts as one of the biggest Tests he has been involved in since his debut four-and-a-half years ago.

“It’s massive,” he said. “This is one of the biggest games we’ve played as a group, so let’s see what it brings out of us here at home.

“I really want to earn another week with the team (in contention). I know things next week are still available (including a Triple Crown) if things don’t go right, but that’s not my mentality, thinking about if things don’t go right.

“I want to earn another week with this group chasing the main goal, and that’s lifting the Six Nations trophy.”

Antoine Dupont has insisted France must focus solely on defeating Scotland and not become fixated on securing the Six Nations title at Murrayfield.

Les Bleus have won all three of their matches so far and will seal back-to-back championship triumphs with a game to spare if they earn a bonus-point win in Edinburgh.

If they do not land the title this weekend, they will have another opportunity against England in Paris next Saturday.

“It’s important to win competitions when you’re in a position to win them,” said captain Dupont at his eve-of-match press conference at Murrayfield.

“Obviously, for many reasons, it will be more than positive to win this tournament, but we still have two games to play and today we’re far from it.

“The goal is to win the match. We know how difficult it is to win here. We don’t need to talk about the quality of the Scottish team, especially since the beginning of this tournament.

“Our main focus is here for the moment. We will have time to see what happens next.”

Scotland’s forwards coach John Dalziel has issued a rallying cry to his squad, challenging them to deliver their best performance of the Six Nations campaign against France.

With Jalibert back, Ramos returns to full-back and Theo Attissogbe to the right wing, while the fly half’s club colleagues Yoram Moefana and Nicolas Depoortere are reunited in the centres after injury.

Another Six Nations Saturday gets underway with a mighty meeting between Scotland and France in Edinburgh and an encounter that could end with this year’s champions known. A bonus point win would be enough for Les Bleus to retain their title with a round to spare – but things are seldom straightforward in this championship, as the hosts have already proved in this campaign.

Kick off is at 2.10pm GMT.
