England coach Tony Smith will not use the 15 players in his World Cup squad involved in Saturday's titanic clash between Leeds Rhinos and St Helens.

Instead he will give them a well-earned rest and use the game to look at players involved in his train-on squad in competitive action.

Harlequins trio Rob Purdham, Louie McCarthy-Scarsbrook and Tony Clubb have all been named in Smith's 18 man squad, while Castleford's Michael Shenton and Salford's Richard Myler, who destroyed the Dons in July's Northern Rail Cup final, should make their debuts.

The squad to face Wales will include eight players named in Smith's 24-man World Cup party, who fly to Australia on Monday, including Warrington's Martin Gleeson who will captain the side.

* England squad to face Wales in the Gillette Fusion International at the Keepmoat: Shaun Briscoe (Hull KR), Peter Fox (Hull KR), Michael Shenton (Castleford Tigers), Paul Sykes (Bradford Bulls), Mark Calderwood (Wigan Warriors), Martin Gleeson (Warrington Wolves), Richard Myler (Salford City Reds), Stuart Fielden (Wigan Warriors), Mickey Higham (Wigan Warriors), Louie McCarthy Scarsbrook (Harlequins RL), Gareth Hock (Wigan Warriors), Ben Westwood (Warrington Wolves), Rob Purdham (Harlequins RL), David Hodgson (Huddersfield Giants), Jamie Langley (Bradford Bulls), Darrell Griffin (Huddersfield Giants), Tony Clubb (Harlequins RL), Ryan Atkins (Wakefield Wildcats).
