All depends on the injury front and how Grimes, Miller and Broad pull up thru the week. Would throw Nankervis in that lot as well because he is clearly injured.
Worst case scenario and all three are injured enough to miss then id be going with the following also giving Nankervis a rest.
FB: Stack - Tarrant - Gibcus
HB: Vlastuin - Balta - Rioli
C; Pickett - RC-D - McIntosh
R: Soldo - Cotchin - Prestia
HF: Cumberland - Riewoldt - Bolton
FF: M Rioli - Lynch - Ryan
INT: Graham - Baker - Sonsie - Brown
Sub: Short.
Ins: Brown, M Rioli, Ryan, Stack, RC-D, Stack, Gibcus, Lynch.
Out: Broad inj, Nankervis inj, Grimes inj, Miller inj, Edwards omitted, Ralphsmith omitted, Short sub.
