There are four personnel changes and a number of positional switches in the back-line as well as a host of changes to the pack as Emerging Ireland seek to maintain their unbeaten status and claim the Nations Cup title.
Paul Marshall comes in for the injured Luke McGrath at scrum half and Ian Keatley replaces his Munster rival JJ Hanrahan in the number 10 jersey.
Stuart McCloskey takes over from Brendan Macken in the centre, linking back up with Eoin Griffin in the partnership that started against Russia last week. Andrew Conway replaces Michael Allen on the left wing with Craig Gilroy and Johne Murphy swapping positions in the back-three.
In the front row John Ryan is retained at loosehead prop and James Tracy comes in for Bryan Byrne at hooker with Michael Bent replacing Ricky Lutton on the tighthead side. David Foley joins Billy Holland in the second row after Michael Kearney was ruled out through injury.
Captain Dominic Ryan returns to the matchday squad after being ruled out of the game against Uruguay due to illness. He is joined in the starting back row by Sean Dougall, who has recovered from a finger injury, and number 8 Robin Copeland.
Sunday's match against Romania will determine the winners of this year's Nations Cup with both sides having recorded two victories to date. Emerging Ireland have a two-point lead over the Oaks at the top of the table. There will be a live stream on www.rugbytv.ro/player.
