Darren Cave switches from inside centre to his more familiar role in the number 13 jersey, with Jared Payne, Craig Gilroy and Luke Marshall, who all scored tries in the Heineken Cup pool match against Treviso at Stadio di Monigo in December, also named in the back-line.
Up front, Ricky Lutton starts at tighthead prop with Rob Herring named at hooker and Tom Court selected at loosehead.
Johann Muller captains the side from the second row where he is joined by Lewis Stevenson who has recovered from the neck injury that he sustained against the Ospreys.
John Afoa has returned to New Zealand due to a family bereavement, while Nick Williams was unavailable for selection.
The game in Parma on Sunday afternoon will be live on the BBC Sport NI website and BBC Red Button.
