Ireland head coach Andy Farrell has named two uncapped players Mack Hansen and Michael Lowry in the 37-man squad for the upcoming Six Nations tournament.
Hansen and Lowry have been impressive for Connacht and Ulster respectively in the ongoing campaign while there has been no places for Harry Byrne, Ciaran Frawley, Simon Zebo and Stuart McCloskey.
Fly-half Johnny Sexton has recovered from his injuries to captain the side for the third successive year in the championship while Joey Carbery has also been named despite sustaining a fractured elbow recently.
"In November we challenged the group to get up to speed quickly so that the team could perform at international level, head coach Farrell said.
"We have a strong squad with competition for places across the board, there is a nice blend of experienced internationals and guys who have had their first taste of this level in the past 12 months.
"The games in November gave us a good foundation to build on and areas where we know we will have to improve," he added. "It will be an exciting championship with so many strong squads and impressive performances across the board during the autumn."
Ireland will kick-start their Six Nations campaign with a clash against Wales at Aviva Stadium on 5th February.
