Teenager Marcus Smith has been included in Eddie Jones' England squad to begin their preparations for the opening match of the Old Mutual Wealth Series against Argentina.
But Harlequins' 18-year-old former Brighton College student is included along with 20-year-old Zach Mercer (Bath Rugby) as an apprentice in the England squad.
Both players won't be named in match day squads but will be involved in England’s training and preparation for the three-match series.
Eastbourne-born Joe Marler (Harlequins) is not been included due to suspension but former Sussex colts Dylan Hartley (Northampton Saints) and Joe Launchbury (Wasps) are included.
England will play Argentina on 11 November at Twickenham Stadium before facing Australia (18 November) and Samoa (25 November).
