Owen Farrell has been unable to train fully with his England team-mates since the 12-6 victory against Wales because of an unspecified leg injury.

Farrell, a mainstay of Eddie Jones’ streak of 24 wins out of 25 games as England head coach, has been limited to a personalised training programme for the past 10 days. Last week, Jones confirmed that Farrell did not participate in contact training with the rest of the team and he, again, sat out the main session on Tuesday.

England remain confident this will not affect his participation in the Calcutta Cup clash against ­Scotland on Saturday and anticipate that he will join in a full-team ­training session on Thursday.

“He’ll train with us on Thursday, so the next training session he’ll be training with us,” Neal Hatley, the scrum coach, said. “Owen is good, he’s been doing an extra bit of ­reconditioning, but he’s good to go. We have a clean bill of health, so everyone is available for selection.”

Farrell made his debut at ­Murrayfield in 2012 and has gone on to become England’s second-highest points scorer behind Jonny Wilkinson. Even more valuable than his goalkicking is the 26-year-old’s influence on the team as a playmaker and defensive leader, as defence coach Paul Gustard ­attested. “He is a massive player in ­attack or defence,” Gustard said.
