Ulster Rugby - one of the seven clubs to have won both their matches in the opening rounds of the 18th Heineken Cup tournament - provide four of the backs for the Ireland XV to play Fiji in the non-cap international at Thomond Park.
The uncapped trio of outside half Paddy Jackson and his Ulster colleagues wing Craig Gilroy and centre Luke Marshall line-up with co-centre Darren Cave - who has won three caps - at the heart of the back line.
With lock Dan Tuohy and flanker Iain Henderson starting in the pack eight Ulster players are in the match day squad in uncapped scrum half Paul Marshall and back row forward Chris Henry as the 1999 European champions and 2012 Heineken Cup finalists are rewarded for their strong start to the season.
Meanwhile Mike Ross, Conor Murray and newly-appointed captain Jamie Heaslip have been retained from the Ireland team that started against South Africa last weekend.
David Kilcoyne, who won his first cap last weekend, will pack down alongside Sean Cronin and Ross in the front row, while Tuohy and the 89-times capped Donncha O'Callaghan will link up in the second row.
Heaslip anchors the scrum with Henderson, a debutant as a replacement against the Springboks, and John Muldoon taking the blindside and openside flanker berths respectively.
