A powerful pack sees Stuart Fielden, Adrian Morley and Jamie Peacock all starting in Christchurch.
Wigan's Sean O'Loughlin will wear the loose forward shirt.
The element of surprise could be provided by Great Britain's interchange bench, with a possible four players in line to make their debuts.
Saints' James Roby, Wigan's Gareth Hock and Hull's Garreth Carvell will all be included to make their debuts.
Another potential debutant could be Jon Wilkin of Saints, who has been bracketed with Lee Gilmour as 17th man.
