Ireland have made 13 personnel changes to their team that beat South Africa 38-3 last week for the match against the Fiji Airways Flying Fijians this Sunday.
Some of the changes are winger Darren Sweetnam, hooker Rob Herring and prop Andrew Porter making their first starts while centre Chris Farrell will make his debut.
Ireland coach Joe Schmidt admits his experimental side face "a real challenge" against Fiji and expects they will face some really tough moments.
He says there is no better way to test people than to throw them into the arena.
Fiji are yet to name their team.
Fiji play Ireland at 6.30am Sunday.
