Ireland have been dealt a blow ahead of their final Autumn Nations Series clash with Argentina after scrum-half Jamison Gibson-Park was ruled out due to injury.
The Leinster half-back, who played a key role in Ireland’s impressive 29-20 win over New Zealand in Dublin on Saturday, has been sidelined with a thigh problem.
It brings to an end a solid month for the New Zealand-born scrum-half as he scored his maiden international try in the 60-5 win over Japan the previous weekend.
Luke McGrath called in
Fellow Leinster player Luke McGrath has been added to Andy Farrell’s squad to provide additional cover.
McGrath is yet to feature under head coach Farrell, having won the last of his 19 Ireland caps as a substitute in the quarter-final loss to the All Blacks at the 2019 World Cup.
The 28-year-old joins Munster pair Conor Murray and Craig Casey as the number-nine options in the Irish camp.
Gibson-Park’s enforced withdrawal guarantees changes in both half-back positions after captain Johnny Sexton was on Monday ruled out for up to six weeks due to twisting an ankle and a knee during the victory over the Kiwis.
Joey Carbery is likely to take the number 10 jersey following his match-winning contribution against the All Blacks, with Harry Byrne and Jack Carty also pushing for inclusion.
The Irish Rugby Football Union has announced that lock James Ryan will skipper the side against Los Pumas in the absence of fly-half Sexton.
Scotland scrum-half George Horne is keeping his fingers crossed he is given a start against Japan in their final Autumn Nations Series clash.
The Glasgow Warriors flyer was on the bench for the Scots’ win over Australia and loss to South Africa, but could well be handed a starting berth this Saturday.
Horne, 26, went over for a hat-trick of tries on his last start, against Russia at the 2019 Rugby World Cup, and may get the nod ahead of Ali Price at Murrayfield.
