Head Coach Wayne Pivac has made three changes to the side with Harry Robinson, Aled Davies and Phil John replaced in the starting XV by Adam Warren, Gareth Davies and Rob Evans respectively.
Robinson and Davies both miss out through injury whilst John moves to the replacements bench.
Speaking ahead of the PRO12 clash Pivac said: "We've just got to prepare for a game to win. Sometimes when you're in the scenarios where you need a point or bonus point win it can disrupt things. We're quite happy to prepare the way we prepare. We've got to back ourselves to win that game.
"We know what the equation is; we're looking forward to it."
Pivac is aware of the danger that Treviso present; "They're a big challenge. They're in exactly the same boat as us. A win guarantees them a place in Europe. We're expecting a big challenge. They had success against us two years ago and that's fresh in the boys' minds.
"That's our aspiration every year to be in Europe, that's certainly what we want to achieve. Total focus is this week and getting the job done.
