Gloucester number eight Luke Narraway will captain the England XV in Sunday's non-cap game against the Barbarians at Twickenham.
Coach Stuart Lancaster has delayed naming his team due to a number of injury concerns, including Northampton scrum-half Lee Dickson who requires shoulder surgery and has been ruled out of this weekend's game and the forthcoming Churchill Cup.
Lancaster said: "We've got a couple of other injuries to assess and we'll have a look at some potential replacements in training against the England Under-20 side. Another 24 hours will give us time to finalise the squad before we move to Pennyhill Park and train at Twickenham on Friday."
He added: "Our preparations have gone well overall and we're pleased to announce that Luke Narraway will captain the side, which is a great reflection of the form and leadership qualities he's demonstrated at Gloucester this season."
Saracens-bound fly-half Charlie Hodgson is likely to start in a back division set to include capped internationals Matt Banahan, Ugo Monye and James Simpson-Daniel.
