Andy Farrell has named a 37-strong Ireland squad for the upcoming Guinness Six Nations, including only 27 of the 34 players capped during the recent three-game Autumn Nations Series. 

Keith Earls, Jordan Larmour, James Lowe, the uncapped Jamie Osborne and Jacob Stockdale are the newcomers in the backs, replacing Robert Baloucoune, Robbie Henshaw and Joey Carbery.

In the pack, Ryan Baird, Gavin Coombes, Iain Henderson, Ronan Kelleher and Dave Kilcoyne all are named on this occasion, with Jeremy Loughman, Kieran Treadwell, Nick Timoney and Max Deegan missing out.

Ireland, which has named 17 backs and 20 forwards for the championship, used 15 backs and 19 forwards across the November program that featured successive wins over South Africa, Fiji and Australia to bolster the No. 1 World Rugby ranking.

Having watched all the other Six Nations countries announce their squads in the past week, Farrell has unveiled his Irish pick ahead of their Feb. 4 opener away to Wales. 

Included are Mack Hansen, Stuart McCloskey, Tadgh Furlong and Caelan Doris. The quartet of players started all three recent test games. 

The inclusion of the uncapped Osborne is recognition by Farrell of the 21-year-old's eye-catching form at Leinster, where he has taken advantage of the absence of the injured Henshaw, who hasn't played since limping out of the Ireland win over Fiji in the first few minutes.

Ireland will fine-tune its Round 1 preparations with a gathering at Quinta da Lago in Portugal, before flying into Cardiff on Feb. 2, two days before they tackle Warren Gatland's Wales at the start of a campaign that continues the following weekend with a home encounter in Dublin versus title-holding France.
