Because players aren't included within the 19 man squad doesn't mean that they won't feature on Saturday. Playing Simon after a hamstring injury would be a risk as we could be down to a 3 man bench...
My 17 for Saturday will be:

Max Jowitt
Craig Hall
Joe Arundel
Reece Lyne
Ben Jones-Bishop
Jacob Miller
Liam Finn
Nick Scruton
Scott Moore
Scott Anderson (2x NRL Grand Final experiences, W 1 L1)
Anthony Tupou
Danny Kirmond
Mikey Sio

Jason Walton (He has surprised me these past few month)
David Fifita
Tirinau Arona
Andy Yates/Mickael Simon

So Crowther and B. Tupou to miss out. Bill picked up an injury, even if he was first that'd be my starting backline ATM.

FWIW, Seems like Warrington fans believe there's a reason why Patton is in the team however I remember him playing us last year and he played very well so there is potential doubt doubt over atleast one Ratchford, Sandow and Gidley...

chester has been good for you hope you beat wire good luck

Pattons playing in their reserves tonight.

I'd be happy for Wire to take a gamble on a not quite fit Sandow, Gidley or Ratchford, than a fully fit Patten.
Then again Terry Campese beat us on wooden legs!
