Louis Ludik, who was rested for the interprovincial game, returns to the side at fullback with Peter Nelson moving to the replacements bench.
Franco van der Merwe misses his first game of the season as he has a chest infection, so Alan O'Connor starts the match in the second row.
Ireland international, Jared Payne, has recovered from injury and is also named among the replacements.
Tommy Bowe, who sustained a dead leg against Leinster, is fit to face the Italian side and is joined by Ludik and Craig Gilroy in the back three.
Darren Cave and Stuart Olding continue in midfield, while Paddy Jackson and Ruan Pienaar maintain their partnership in the half backs.
Wiehahn Herbst and Callum Black start either side of captain, Rory Best, while Dan Tuohy, who signed a new three-year contract with Ulster this week, is named alongside O'Connor in the second row.
The back-row is unchanged from last week's match with Roger Wilson at Number 8, Robbie Diack at blindside and Clive Ross selected at openside.
Forwards, Rob Herring, Andrew Warwick, Bronson Ross, Lewis Stevenson and Sean Reidy join backs Paul Marshall, Payne and Nelson on the replacements bench.
The game is live on BBC 2 Northern Ireland.
