Eddie Jones's men were hit with a handful of injuries after last weekend's Premiership rounds, but plenty of hopefuls will still have a chance to impress before the January 18 announcement of the Six Nations squad.
Charlie Ewels (hamstring), Piers Francis (concussion), Jonathan Joseph (dead leg), Jack Nowell (ankle) and Harry Williams (concussion) were all absent from the camp, while lock Courtney Lawes was already ruled out for personal reasons.
Giant London Irish wing Joe Cokanasiga and Bath's Henry Thomas have been called up as injury replacements.
