Connacht hooker Dave Heffernan has been called up to the Irish squad in advance of next Saturday's Six Nations pivotal round two game against France in the Stade de France (kick-off 5.45pm local time/4.45pm Irish).
He replaces Rob Herring, who has been ruled out of consideration due to a calf injury. The squad has been reduced to 36 players as Keith Earls continues his hamstring rehab in Munster over the coming weeks and his progress will be assessed as the championship progresses.
Ulster trio Michael Lowry, Robert Baloucoune and Nick Timoney have rejoined the squad having featured for Ulster against Connacht in the URC on Friday evening.
Meanwhile, France have recalled all but one of the 14 players released last weekend in restoring their squad to its original 42 players.
The Toulouse lock Thibaud Flament replaces Florian Verhaeghe of Montpellier. The prop Mohamed Haouas is thus not recalled after his conviction and suspended sentence of 18 months in jail for his role in a series of burglaries of tobacconists in 2014.
Saturday’s game at the Stade de France will be broadcast live on Virgin Media and ITV and RTÉ Radio.
