As the second weekend of Six Nations action draws to a close, Sportsmail's Chris Foy digests the best of the offerings around the grounds...

EXCLUSIVE: The Six Nations are facing a battle to win support from clubs and players for an expanded tournament featuring South Africa.

There have been concerns over Biggar's concussion record, having taken two blows to the head during the World Cup against Australia and Fiji in September.

Leigh Halfpenny reckons Wales can roll back the clock and repeat their feats of 2013 this year by winning the Six Nations title, despite losing to Ireland in their last encounter.

The Welsh face an unbeaten French side in Cardiff on Saturday. Wayne Pivac's side come into the game on the back of a defeat in Dublin to the Irish - their first Six Nations loss since 2018.

Wayne Pivac believes his wise Wales will overcome French flair on Saturday in the Six Nations having picked the most experienced line-up to grace the championship.

The last two Tests between Wales and France have been edge-of-the-seat thrillers. Both were won by wily Wales just when all looked lost:

If on Saturday the tide has turned against Wales, the French are flooding through in attack and causing chaos it will be the old men of the sea who guide those in red to calmer waters.

WILL KELLEHER AT THE PRINCIPALITY STADIUM: Wayne Pivac was left livid with two decisions costing Wales a win over France as they lost at home in the Six Nations for the first time in three years.

Shaun Edwards stood in the bowels of the Principality Stadium wearing the quiet contented look of a man who had just transformed a team that for years had an attitude problem.

As Sportsmail reported last month, full back Liam Williams has made a swift departure from under-fire European and English champions Saracens after their salary cap disaster.

Liam Williams, Josh Navidi and George North all set to be fit for selection for boss Wayne Pivac as Wales were handed a triple boost before taking on England at Twickenham on March 7.

EXCLUSIVE BY WILL KELLEHER: Welsh victories at Twickenham are rare but much-celebrated occasions. Sportsmail spoke to those involved in the most recent triumphs.

Wales will be hopeful Dan Biggar does not spark a backline injury crisis ahead of their Six Nations match against England after going off early for Northampton on Saturday against Saracens.

Sky are in line to secure a £300million agreement to screen the competition from 2021, leaving terrestrial channels BBC and ITV on the margins with potentially huge implications for the sport.

Wales wing Hallam Amos will miss the rest of the 2020 Guinness Six Nations due to a knee injury. Amos sustained the injury during the Cardiff Blues' Guinness PRO14 victory over Benetton.

Manu Tuilagi is England's master of destruction on the pitch - and he is building an equally fierce reputation on the chess board.

Sam Warburton may have seen the Wales-England rivalry become friendlier in recent years but he called on his players to make themselves heroes at Twickenham on Saturday.

SIR CLIVE WOODWARD: There are some things much more important than sport, and when something like the coronavirus comes along rugby has to step into line.

Anthony Watson and Mark Wilson will make their first England appearances since the World Cup final in Saturday's Guinness Six Nations match against Wales at Twickenham, the RFU has announced.

Liam Williams will play his first Test for four months in the Six Nations against England, coming straight into the starting team as Wayne Pivac rings the changes for Wales.

Josh Navidi once turned All Blacks heads and has now been backed to leave England blue too at Twickenham. He had hamstring trouble but is now fit to start on Saturday.

England became Triple Crown winners with a rollercoaster victory against Wales at Twickenham.

MIKE BROWN: Players love seeing what grenades Eddie Jones throws during his press conferences. Sometimes they will be watching on social media to see what he comes out with.

Sportsmail's Chris Foy gives his thoughts on the Six Nations with England now sitting top of the table following their win over Wales and France's defeat to Scotland on Sunday.

WILL KELLEHER AT TWICKENHAM: Justrin Tipuric called for calm after Wales' third consecutive defeat - making this their worst Six Nations run since 2007.

Joe Marler has given his response to the storm over his manhandling of Alun Wyn Jones's genitals with Piers Morgan among those weighing into the debate on Twitter.

France's Six Nations clash against Ireland joins England v Italy in being pushed back, although RFU chief Bill Sweeney says he sees no reason why Wales v Scotland can't go ahead.

England are facing a triple ban after Joe Marler, Manu Tuilagi and Courtney Lawes were all cited following Saturday's ill-tempered victory over Wales.

Wales are still livid at Joe Marler for his grabbing of Alun Wyn Jones' genitals with Wayne Pivac saying there is 'no place in the game' for the England prop's act.

In a shambolic development on Friday afternoon the final match of the Championship was officially postponed while Scotland were warming up for their captain's run ahead of Saturday's game.

WILL KELLEHER: George North has had enough. Not of rugby, nor of playing for Wales but of them. North has had it with online trolls who spout vile bile at him and his family.

The former Wales international Jamie Roberts had been playing for Super Rugby side Stormers in South Africa but flew home to the UK to help after the rugby season was put on hold.

With sport a long way from being permitted, rugby is bracing itself for catastrophic losses and Six Nations countries are desperate for the November Test matches to go ahead.

COMMENT: It is a sad fact that the main barrier to rugby's progress lies here; in the home nations and those other centres of the sport's narrow European landscape - France and Italy.

England forward Joe Marler will be free to play rugby when sport returns after the coronavirus shutdown - despite being handed a 10-week ban for squeezing Alun Wyn Jones' genitals.

SPORTS AGENDA BY MIKE KEEGAN: England's footballers may well have been delighted last week when the FA announced a multi-year sponsorship deal with food delivery app Deliveroo.

Steve Smith was already the pantomime villain for England fans but he has riled them even more following Australia's celebrations after they retained the Ashes on Sunday.

England have named an unchanged squad for the fifth and final Ashes Test at the Oval as Joe Root looks to salvage a consolation win after Sunday's disappointment of failing to regain the Ashes.

Sportsmail columnists Nasser Hussain, David Lloyd, Lawrence Booth and Paul Newman answer the big questions for England's Test team after they failed to regain the Ashes.

Archer was impressive at Lord's and then took six wickets in an innings at Headingley but struggled to replicate that form at Old Trafford and McGrath has questioned his attitude.

Justin Langer rejected suggestions Australia's Ashes celebrations at Old Trafford targeted England's Jack Leach for mockery, insisting the on-pitch party was a 'two out of 10' performance.

Members of the Australian cricket team were understood to be trying to contact Jack Leach on Tuesday night following suggestions that they mocked him during their Ashes celebrations.

NASSER HUSSAIN: What happens on the field over the next five days is hugely important because a 2-2 scoreline in the Ashes would be far better for England than 3-1 to Australia.

LAWRENCE BOOTH AT THE OVAL: Jofra Archer picked up the second six-wicket haul of his fledging Test career as England gave themselves hope of squaring the Ashes on a dramatic day at The Oval.

Joe Root knows England have 'something special' on their hands in Jofra Archer but has already started the job of managing expectations around the breakout star of the summer.

England have set a minimum target of 425 points in their quest to reach the inaugural World Test Championship final at Lord's in 2021. Joe Root's team claimed 56 from the 2-2 draw in the Ashes.

Archer took 47 wickets in his first season of international cricket, including 22 at just 20 apiece in the Ashes , leaving new-ball partner Broad to lavish praise on his 'incredible attributes'.
