In the back division, Tom Williams has recovered from a shoulder injury and starts at full back ahead of Gavin Duffy, who drops to the bench.

In the pack, James Hayter starts at hooker in place of Ace Tiatia, while Simon Maling returns having missed the game against Irish due to concussion. Maling will partner Jim Evans in the second row, with Simon Miall dropping to the bench.
