Fiji coach Glen Ella, whose management team includes former Leinster forwards coach Mike Brewer, has made five changes to the side that lost 23-10 to Scotland at Murrayfield.
The experienced Norman Ligairi returns at full-back, replacing the benched Josh Matavesi, and Nasoni Roko comes in for Napolioni Nalaga on the left wing.
There are three changes up front, with Asaike Tarogi and Viliame Seuseu drafted into the front row, and Apolosi Satala joining his Gloucester team-mate Akapusi Qera in the back row.
Notably, Ulster's popular winger Timoci Nagusa has gained a place on the bench having linked up with the squad in Dublin earlier in the week.
Nagusa has played three times for Fiji, his last appearance coming in June of this year when he scored two tries in the Pacific Nations Cup win over Tonga.
Fiji captain Seremaia Bai, who plays his club rugby for French side Clermont Auvergne, is one of the current players who lined out in the 64-17 defeat to Ireland on their last visit to Dublin in November 2002.
Ligairi, out-half Nicky Little and lock Ifereimi Rawaqa also featured in that game at Lansdowne Road.
