The big Kiwi back row forward made his debut for the Blues against Exeter in a pre season friendly, but the match against the former Heineken Cup champions will be his competitive debut having sat out last Saturday's win over Edinburgh.
The Blues will look to build on the victory when they travel to the Irish capital but know it will be a big ask with their only previous victory in Dublin in the Magners League was 22-18 against Leinster at Donnybrook in March 2004
There are three other changes in the pack to the starting XV that defeated Edinburgh with Tom Davies, Deiniol Jones and Sam Warburton all starting having been on the bench last weekend.
The only change in the backs sees Dafydd Hewitt coming in for Tom Shanklin at centre.
