England have named several uncapped players in their squad to prepare for next Sunday's clash against the Barbarians at Twickenham.
The rookie contingent includes Exeter flanker Tom Johnson, who was a key performer for the Chiefs during their impressive debut Aviva Premiership campaign, two 20-year-old props in Harlequins' Joe Marler and Newcastle's Kieran Brookes and promising Gloucester centre Henry Trinder.
But the group also features 11 players with senior England experience, among them Bath threequarter Matt Banahan, Saracens-bound fly-half Charlie Hodgson and Harlequins wing Ugo Monye.
There are eight players from this season's English European finalists Northampton and Quins, with England Saxons head coach Stuart Lancaster taking charge of preparations for the non-cap game.
No players from Leicester or Saracens were considered because of next Saturday's Premiership final between the clubs at Twickenham.
The game comes less than a week before England Saxons launch their Churchill Cup campaign, which they start against the United States at Northampton.
Lancaster said: "It is a great opportunity for all the players who are looking to force their way into Martin Johnson's plans for the World Cup, and those who will go on to defend the Churchill Cup with the England Saxons next month."
