Rob Kearney meanwhile will have to make do with a place on the bench, while James Lowe fails to make the matchday squad. Jordan Larmour will instead start at fullback.

Elsewhere Rhys Ruddock will captain the side, while Sean O’Brien gets the nod over Dan Leavy who has only recently returned from injury.
