Wigan Warriors hooker Michael Mcilorum is set to make his comeback from a 14-month lay-off with a broken and dislocated ankle, while winger Joe Burgess and captain Sean O'Loughlin are also set to return and centre Anthony Gelling will have a chance to prove his fitness after missing the last two matches. Forward Tony Clubb is out with a lower back problem.
St Helens caretaker coaches Jamahl Lolesi and Sean Long have called up forward Luke Thompson in place of Dominique Peyroux and also included in their initial 19-man squad, 20-year-old winger Regan Grace, who has yet to play in Super League. Hooker James Roby remains sidelined with a knee injury.
