All depends on Arundel, really. If Crooks was available I'd definitely say replace him, but without that option I'd rather not move Whiting. Gentle will have the best idea whether or not to give Arundel another chance by how he's reacted in training, so for me it would either be:
McDonnell
Lineham
Arundel
Yeaman
Briscoe
Holdsworth
Horne
Lynch
Houghton
O'Meley
Tickle
Westerman
Pitts
Heremaia
Watts
Johnson
Whiting
Or Whiting to centre, Bowden on the bench. I don't even want to contemplate Holdsworth not playing.
