Ulster go into the match on the back of consecutive victories over Zebre and Edinburgh and recorded a 32-13 triumph over this weekend's opposition in September.
And they are set to welcome back star duo Johann Muller and Ruan Pienaar for the sold-out Ravenhill clash. Muller has not played since suffering a calf injury against Cardiff Blues in October, while Pienaar returns from international duty with South Africa.
Kiwi full back Jared Payne will also be assessed to determine his availability following a groin injury but Rory Best, Iain Henderson and Paddy McAllister are definitely out of the encounter and so is Tommy Bowe. The Ireland and Lions wing faces between four and six weeks on the sidelines with a muscle tear and may not even feature in Round 5 against Montpellier next month.
Treviso have never overcome an Irish opponent in the Heineken Cup but have claimed some notable scalps in recent seasons, including those of the Ospreys, Biarritz Olympique and Perpignan. They warmed up for the daunting trip to Ravenhill with a hard-fought 26-26 draw with the Blues on home soil.
Once again discipline let the Italian outfit down, with Gareth Davies slotting a late penalty to take a share of the spoils. And they will need to keep their cool at Ravenhill, with Paddy Jackson and Pienaar both accomplished goal-kickers.
