SAINTS hooker James Roby has dropped out of Friday's squad for the clash with Wakefield.

He is replaced in the 19 by new boy Shannon McDonnell, who arrived at Saints today.

That would indicate - if all is well - that the Australian will drop straight into the team at full back.

Looking at the squad, it appears likely that the hooking role will be taken on by Duggie Charnock, possibly in conjunction with Mark Flanagan.

Saints: Tommy Makinson , Jordan Turner, Josh Jones, Adam Swift, Travis Burns, Luke Walsh, Mose Masoe, Kyle Amor, Jon Wilkin, Louie McCarthy-Scarsbrook, Alex Walmsley, Mark Flanagan, Mark Percival, Luke Thompson, Greg Richards, Andre Savelio, Lewis Charnock, Matty Fleming, Shannon McDonnell.

Wakefield: Craig Hall, Chris Riley, Reece Lyne, Richard Owen, Jacob Miller, Tim Smith, Nick Scruton, Paul McShane, Ali Lauitiiti, Danny Washbrook, Pita Godinet, Matt Ryan, Mickael Simon, Daniel Smith, Jon Molloy, Jordan Crowther, Tom Johnstone, Joe Arundel, Ben Kavanagh.
