Farrell has endured an injury-hit season so far and suffered a setback in training last week, with his club Saracens revealing he was set to see a specialist about the unspecified issue.

While he is all but ruled out of the Six Nations opener against Scotland on February 5, England are yet to confirm if Farrell can return after the Calcutta Cup clash.

Nevertheless, Ford is back in the selection to make up for Farrell's absence against Scotland, with the Leicester Tigers fly-half seemingly set for his 78th cap.

Ford has not played for England since the 32-18 Six Nations defeat to Ireland last March, with Marcus Smith's emergence nudging him down the pecking order, but he has the chance to stake his claim once again.

Also in Monday's squad update, England confirmed May has withdrawn from the squad with a knee injury, while Courtney Lawes – initially one of the favourites to deputise as captain in Farrell's stead – must sit out training this week because of head injury protocols.

Nick Isiekwe has joined up with the squad as cover for Lawes, while Elliot Daly is in for May.
