Problems mount for England
England could face a hooking crisis after being hit by two more withdrawals from coach Tony Smith's World Cup train-on squad.
Bradford number nine Terry Newton has joined Warrington's Jon Clarke on the sidelines, taking to five the number of injured Great Britain internationals.
Clarke pulled out on Saturday after breaking an arm in Warrington's play-off defeat at Catalans Dragons while Newton and his Bradford team-mate Andy Lynch were ruled out with shoulder injuries.
Another Bradford forward, Sam Burgess, and Wigan loose forward Sean O'Loughlin had earlier pulled out of contention, also with shoulder injuries.
Newton and Clarke were the starting hookers for Great Britain in last year's Test series against New Zealand but James Roby, of St Helens, was chosen for the mid-season international against France in June.
Roby is assured of his World Cup place and could be the only specialist hooker unless Smith opts to recall Wigan's Mickey Higham.
Meanwhile, Bradford scrum-half Paul Deacon is poised to make his international comeback after being one of six players added to Smith's train-on squad.
