Chessum has won 34 previous caps for England and toured with the British and Irish Lions in Australia in the summer
Under-pressure England have made a solitary change to their line-up to face France in the final round of the Six Nations on Saturday with Ollie Chessum coming into the back row.
The versatile Chessum, 25, started the first three games of England's campaign in the second row but will add weight, ball-carrying power and a useful line-out option as blind-side flanker.
With Tom Curry out with a calf injury sustained in the warm-up of their loss to Italy, Guy Pepper shifts to open-side.
Sam Underhill, who came into the starting line-up as a last-minute replacement for Curry in Rome, drops to the bench.
