Molenaar leads a side similar to the one that defeated Leicester last Monday but first team call ups over the weekend mean that the likes of Tommaso d'Apice, Peter Buxton and Gareth Evans are unavailable.
Kick off at Kingston Park is at 7pm.

Martyn Thomas; Steph Reynolds, Billy Burns, Tim Molenaar (capt), Ian Clark; Tim Taylor, Brad Field; Yann Thomas, Nathan Stroud, Dario Chistolini; Will Graulich, Elliott Stooke; Ross Moriarty, Rob Langley, Matt Cox
