Former Bath captain John Hall has been appointed to England's management team for the RBS 6 Nations Championship.
Hall, who won 21 England caps between 1984 and 1994, will provide video analyis after the contract for his company - Performance Group International Rugby - was extended to include the senior team.
PGIR has carried out video analysis for the England sevens and England age group sides during the past three years.
Elsewhere, physiotherapist Mike Snelling and masseur Paul Frawley join England's medical staff with immediate effect, working with England team doctor Simon Kemp and physio Barney Kenny.
Snelling and Frawley have assisted the Saxons and Sevens squads in recent seasons.
Former England masseur Richard Wegrzyk, meanwhile, will continue to work with the Rugby Football Union's elite rugby department, acting as England sevens squad masseur for the remaining six tournaments in this year's International Rugby Board world series.
Wegrzyk previously worked under contract as a masseur for the senior England squad, and was part of the management team for 160 matches.
