Having come through a full 80 minutes last weekend, flanker Sean O’Brien is named at blindside in an experienced back row that includes Butler and veteran captain John Muldoon.
Jack Carty is named at out half where he will form a half back pairing with Caolin Blade.
The squad is also boosted by the return of Niyi Adeolokun from injury and Ultan Dillane from international duty, with both named among the replacements. Dillane will return to Irish camp after the clash in Italy.
The clash with Benetton on Saturday will form the first leg of a tour for Connacht which will take mostly the same personnel on to Bloemfontein in South Africa to play the Cheetahs on Saturday 3rd of March.
Speaking ahead of the two away fixtures, Head Coach Kieran Keane emphasised the importance of having depth in the squad. “We have a number of players coming back from injury which will be a big boost against Treviso on Saturday. They are on a great run of wins and I’m sure they will be targeting us especially when they have been so competitive at home this season”, Keane said.
“The majority of the squad will travel on to South Africa, but we have put plans in place for replacements to join the squad after the game in Italy. These two games will really test the depth of our squad and we will need to be at our best if we want to win them”, he added.
