Courtney Lawes steps up as captain in the absence of Owen Farrell, with Eddie Jones changing up his backline.
Manu Tuilagi is back at centre, with Harlequins’ Marchant shifted out from his preferred centre role to the wing. That means Max Malins and Adam Radwan start from the bench.
Marcus Smith will look to work his magic again from fly-half, with Henry Slade, a vice-captain alongside Tom Curry, primed to feature at outside centre.
