Jones kept faith with the same 23 players he named for the 15-9 victory over Scotland at Murrayfield on Saturday, with Beaumont and Itoje the only additions.
Wasps centre Elliot Daly and Gloucester flanker Matt Kvesic were allowed to return to their clubs, England said in a news release on Tuesday.
Sale's Beaumont is a powerful number eight in the mould of his lock-forward father, one of England's most iconic players who led his country to the grand slam in 1980 and captained the British and Irish Lions in the same year.
Saracens' Itoje is a highly-rated lock/flanker and former England under-20 captain.
