Ireland have stuck with the starting XV narrowly beaten by England for Saturday’s Guinness Six Nations title decider against Scotland in Dublin.

Andy Farrell’s men will retain the championship crown by avoiding defeat or securing two losing bonus points against the Scots at the Aviva Stadium.

Calvin Nash has overcome the head knock which forced him off inside five minutes of the last-gasp 23-22 loss at Twickenham to retain his place on the right wing.

Garry Ringrose, who is yet to feature in this year’s championship following a shoulder issue, is named among the replacements.

Farrell’s bench shows a five-three split of forwards and backs after the six-two selection in south-west London backfired because of head injuries suffered by Nash and his replacement Ciaran Frawley.

Versatile back Frawley drops out of the 23, replaced by fly-half Harry Byrne, while lock Iain Henderson makes way to accommodate the returning Ringrose.

Although Ireland’s pursuit of successive Grand Slams was ruined last weekend, they remain in a strong position at the top of the championship table, having racked up four bonus points and a vastly-superior points difference on each of their rivals.

A defeat without any bonus points could also be sufficient for the title, but would be dependent on the result of England’s trip to France in the final match of ‘Super Saturday’.

Gregor Townsend’s Scots are also mathematically still in the mix. However, following a shock loss to Italy, securing the Triple Crown looks to be the extent of their realistic ambitions.

Leinster trio Andrew Porter, Dan Sheehan and Tadhg Furlong once again pack down in Ireland’s front row, ahead of locks Joe McCarthy and Tadhg Beirne.

Captain Peter O’Mahony retains the blindside flanker role, despite his costly second-half yellow card against England and strong competition from Ryan Baird, with Josh van der Flier at openside and Caelan Doris lining up at number eight.

Jamison Gibson-Park and Jack Crowley continue as the half-back pairing, while Bundee Aki partners Robbie Henshaw in midfield.

Left wing James Lowe, who claimed Ireland’s two tries at Twickenham, and full-back Hugo Keenan complete the starting line-up.

Ireland have won 13 of the last 14 meetings with Scotland, including nine in a row following a decisive 36-14 pool-stage success at last year’s Rugby World Cup in France.

Ronan Kelleher, Cian Healy, Finlay Bealham, Baird, Jack Conan and Conor Murray join Byrne and Ringrose on the bench.

Ireland team: H Keenan (Leinster); C Nash (Munster), R Henshaw (Leinster), B Aki (Connacht), J Lowe (Leinster); J Crowley (Munster), J Gibson-Park (Leinster); A Porter (Leinster), D Sheehan (Leinster), T Furlong (Leinster), J McCarthy (Leinster), T Beirne (Munster), P O’Mahony (Munster, capt), J van der Flier (Leinster), C Doris (Leinster).

Replacements: R Kelleher (Leinster), C Healy (Leinster), F Bealham (Connacht), R Baird (Leinster), J Conan (Leinster), C Murray (Munster), H Byrne (Leinster), G Ringrose (Leinster).

Ireland kept their quest for successive Guinness Six Nations Grand Slam titles on track by brushing aside spirited Wales with a dominant 31-7 victory in Dublin.

Andy Farrell’s men backed up crushing wins over France and Italy with a third consecutive bonus-point triumph to keep themselves in pole position for further championship glory.

First-half tries from Dan Sheehan and James Lowe paved the way for the reigning champions to equal England’s tournament record of 11 wins in a row.

Wales avoided embarrassment at the Aviva Stadium and briefly threatened an improbable fightback thanks to a second-half spell which brought a penalty try and a yellow card for Tadhg Beirne.

But a first Test try for stand-in Ireland full-back Ciaran Frawley broke their resolve before Beirne atoned for his earlier error by securing the bonus point at the death on an afternoon when flawless fly-half Jack Crowley kicked 11 points.

Ireland’s ominous march towards another clean sweep continues next month against England and Scotland, while winless Wales host France in round four ahead of a possible wooden spoon shoot-out with Italy.

A largely inexperienced Wales team crossed the Irish Sea as overwhelming underdogs on the back of narrow defeats to the Scots and Steve Borthwick’s side.

Visiting head coach Warren Gatland insisted he travelled with belief rather than hope and urged his players to make “everything uncomfortable” for the fancied hosts.

Wales’ bid to disrupt began with some colossal defending as the home team’s early dominance was initially rewarded only by a long-range Crowley penalty.

Yet Ireland’s well-oiled machine persisted with wave after wave of attack to break down the staunch resistance and take control of the scoreboard.

Hooker Sheehan powered over at the end of a line-out maul in the 21st minute to claim his fourth try of the tournament before Calvin Nash later teed up Lowe to touch down in the left corner.

Wales finally enjoyed some forays into Ireland’s 22 just before the break.

But Sam Costelow’s decision to kick a penalty to the corner failed to pay off, while a couple of costly fumbles ensured they went into half-time scoreless for a third match on the bounce, at 17-0 down.

Any potential fears Wales had of joining Italy in being nilled in Dublin were extinguished within three minutes of the restart as Tomos Williams’ quick tap penalty led to a momentum shift.

Italian referee Andrea Piardi awarded a penalty try at the end of a lengthy review of a collapsed maul on Ireland’s line, with Beirne sent to the sin bin for illegally changing his bind.

Fired-up Wales were well and truly in the ascendancy at that stage but failed to make further inroads on the scoreboard in Beirne’s absence before Ireland restored order.

After the bulldozing Bundee Aki was denied a try on review for Robbie Henshaw’s knock on, Frawley, deputising for the injured Hugo Keenan, gleefully dived under the posts to celebrate his first Test start in style.

Wales came close to a consolation score in the closing minutes, during which Ireland replacement James Ryan was sent to the sin bin.

Yet, with Beirne’s late finish compounding their misery, they ultimately slipped to a 10th defeat from their last 11 Six Nations fixtures as their wait for a first championship win in Dublin since 2012 goes on.

Ciaran Frawley will make his first Test start in Ireland’s Guinness Six Nations clash with Wales after being selected in place of injured full-back Hugo Keenan.

The versatile 26-year-old won his two previous caps as a replacement, including playing the final four minutes of the championship curtain-raiser away to France.

Keenan has been virtually ever-present in his country’s number 15 jersey during the past three years but will miss Saturday’s match in Dublin due to a knee injury suffered in the round-two victory over Italy.

Head coach Andy Farrell, who has included uncapped Munster prop Oli Jager among the replacements, has made seven personnel changes to his starting XV from the 36-0 win over the Azzurri Italy on February 11.

Captain Peter O’Mahony, prop Tadhg Furlong and centre Bundee Aki return following injuries, while lock Tadhg Beirne, scrum-half Jamison Gibson-Park and flanker Josh Van Der Flier are also recalled.

Second-row James Ryan, flanker Ryan Baird, number eight Jack Conan and centre Stuart McCloskey drop to a bench containing a six-two split of forwards and backs.

Prop Finlay Bealham and scrum-half Craig Casey have been left out of the matchday 23 after starting against Italy.

Lock Iain Henderson, who suffered a foot injury playing for Ulster last weekend, is not involved, while centre Garry Ringrose remains absent after missing the opening two rounds with a shoulder issue.

Frawley has been battling Jack Crowley and Harry Byrne for action at fly-half but Farrell has limited back-up options at full-back due to Jimmy O’Brien and Mack Hansen being ruled out of the entire tournament.

The full debutant has played a total of just 44 minutes of international rugby, during cameos in last summer’s World Cup warm-up win over Italy and the 38-17 victory over Les Bleus at the start of the month.

Crowley continues in the number 10 role, partnering Gibson-Park, with Aki and Robbie Henshaw in midfield and Calvin Nash and James Lowe retained on the wings.

In the front row, returning tighthead Furlong will pack down alongside Leinster team-mates Andrew Porter and Dan Sheehan, ahead of the second row pairing of Joe McCarthy and Beirne.

Caelan Doris, who stood in as skipper last time out, reverts from openside flanker to number eight. Van der Flier returns to the number seven role, while O’Mahony is back in at blindside flanker.

Hooker Ronan Kelleher, prop Cian Healy and scrum-half Conor Murray complete the bench.

Ireland are seeking a third successive win in this year’s championship – and an 18th in a row at home – after launching their title defence with back-to-back bonus-point victories over France and Italy.

Opponents Wales began with narrow defeats to Scotland and England and have not won a Six Nations fixture in Dublin since 2012.
