Full-back Michael Platt and 18-year-old forward Sam Burgess are chasing first caps while Paul Deacon, Andy Lynch and Terry Newton take the squad size to 18.

Warrington's teenage winger Kevin Penny, and Wakefield duo Matt Blaymire and prop Richard Moore are also in.

Coach Tony Smith has also called up Huddersfield pair Kevin Brown and Stephen Wild but there is no place for Giants captain Chris Thorman.

Penny, who gave up a promising basketball career to play rugby league, was recently named in the Super League Dream Team after making only 12 full appearances for the Wolves.

Blaymire and Moore were both playing National League rugby for York last year but played key roles in the Wildcats' successful season.

Smith will announce his final squad after the Grand Final on 13 October.

Initial Great Britain squad: Matt Blaymire, Jamie Rooney, Richard Moore (Wakefield), Kevin Brown, Stephen Wild (Huddersfield), Sam Burgess, Paul Deacon, Andy Lynch, Terry Newton, Michael Platt (Bradford), Jon Clarke, Adrian Morley, Kevin Penny, Ben Westwood, Martin Gleeson (Warrington), Andy Coley (Salford, now Wigan), David Hodgson (Salford,now Huddersfield), Paul Sykes (Harlequins, now Bradford).
