What could Ireland's Six Nations squad look like?

It is not quite a new era for Ireland heading into this Six Nations, but it does feel like a new chapter.

With head coach Andy Farrell now on duty with the British and Irish Lions, Simon Easterby will take charge for this year's tournament.

Ireland are aiming to become the first team to win three Six Nations titles in a row.

It will be a big ask for Easterby, but what could his first Ireland squad look like?

He will name it on Wednesday, and BBC Sport NI takes a look his options.

If Ireland are to make history with three Six Nations titles, they will need the players who have delivered on the big stage.

It is expected that consistency will be key for Easterby and all the big hitters will remain.

Caelan Doris will lead a whole host of Leinster team-mates, including the likes of Andrew Porter, James Ryan, Garry Ringrose, Robbie Henshaw, James Lowe and Hugo Keenan.

Key prop Tadhg Furlong's return from injury is timely, especially now Ulster's Tom O'Toole is suspended for the opening two matches, but hooker Dan Sheehan has yet to return to action.

While Leinster will dominate, Munster are also likely to be represented in the squad with Tadhg Beirne, Conor Murray, Jack Crowley and Calvin Nash all squad regulars.

Prop Oli Jager could be recalled after missing November's Tests through injury, but Peter O'Mahony is currently sidelined and time is ticking ahead of Ireland's opener on 1 February.

Connacht will be represented by centre Bundee Aki, prop Finlay Bealham and wing Mack Hansen, who will be free to play against England when his suspension ends.

This will not be the first time that Easterby has taken charge of an Ireland side.

In September, he led a youthful Emerging Ireland side on a tour of South Africa for the second time in three years.

Three of the squad went on to earn senior caps in November's internationals. Highly-rated fly-half Sam Prendergast is not only in contention for the squad, but also the starting jersey in a battle with Jack Crowley and Ciaran Frawley.

Gus McCarthy capitalised on a senior injury crisis at hooker and made an explosive debut against Fiji, while Ulster's Cormac Izuchuwku also had a solid first cap against the Pacific Islanders.

But who else could potentially be selected for the Six Nations?

Prop Thomas Clarkson also earned a debut in the autumn, while Alex Kendellen captained Emerging Ireland in South Africa and is now a regular starter for Munster.

He is tipped for a big future and was in the wider training squad for the autumn series.

While Ulster's form has been poor, centre Jude Postlewaite could force his way into contention in a stacked centre area and prop Scott Wilson could be a beneficiary of O'Toole's suspension.

It is no secret that Ulster's form has been patchy at best this season as Richie Murphy's side sit eighth in the United Rugby Championship and are winless in Europe.

Forwards Iain Henderson, who provides plenty of experience, and Cormac Izuchuwku are two players who will likely be named by Easterby in the extended panel.

After that, the argument for Ulster players making it into the squad is not helped by a lengthy injury list.

Jacob Stockdale, Stuart McCloskey join Robert Baloucoune, Michael Lowry and James Hume have all featured for Ireland recently but are all out through injury, which has been detrimental to Ulster's form.

International hookers Rob Herring and Tom Stewart have also been sidelined, while O'Toole is suspended for Ireland's opening two matches against England and Scotland.

As mentioned above, Wilson and Postlethwaite are an outside shout for selection, as is Munster's Tom Farrell, who could be an option to take the place of the injured McCloskey in the squad.

Leinster's Jamison Gibson-Park was Ireland's number one scrum half under Andy Farrell and that is unlikely to change under Easterby.

The question is more over who will be next in line to be back-up to the 32-year-old, who has had a number of injury concerns in the past six months.

Craig Casey had appeared to have taken that mantle off Munster team-mate Conor Murray, but the 25-year-old is set to miss the tournament with a knee injury.

Murray is the obvious candidate to be Easterby's number two, but who else could make the squad?

Connacht's Caolin Blade and Ulster's Nathan Doak made it into squad for the summer tour of South Africa.

Doak remained uncapped and Blade, who has fallen behind the in-form Ben Murphy in Connacht's pecking order, did not add to his two Ireland appearances.

Luke McGrath is Gibson-Park's deputy at Leinster and is an option as he looks to win a first cap since 2020 while a recall for Ulster's John Cooney would be a surprise at best.
