They wrap up their European campaign for the calendar year at the Sportsground on Friday night when Rugby Rovigo visit.
Michael Bradley's men beat the Italians 35-20 away last weekend and a second successive bonus point win would do nicely in round 4.
Bradley said: "We were obviously very pleased with the result last weekend. We went to Rovigo looking for a win in order to keep our qualification hopes alive so to have got the bonus point is a big boost to us.
"It was a tough game as Rovigo defended heroically but the match was hampered by a very heavy pitch after a lot of wet weather so it's difficult to gauge what sort of game we are going to see this weekend.
"We showed some good continuity play and put together a lot of phases which is a positive we'll take forward, as well as our scrummaging, which was particularly strong.
"Of course you're always looking to improve but there's nothing I took out of the game as an area of concern.
"We have a couple of injury worries. Johnny O'Connor is ruled out and Keith Matthews and Ronan Loughney both picked up knocks (in Italy) but I think we have enough depth in the squad to cover their possible absence."
