Owen Farrell was passed fit to face Scotland in the Calcutta Cup clash at Twickenham on Saturday following a leg injury.
Farrell, England's first-choice goal-kicker, has been central to the team's run of 17 successive Test wins and was named Thursday at inside centre.
But it then emerged he had suffered an unspecified leg injury and the playmaker missed training on Friday.
Farrell was present for kicking practice conducted by England great Jonny Wilkinson on Friday but was only seen going through the motions of technique rather than striking the ball.
But with Six Nations leaders England not obliged to confirm their side until an hour before Saturday's kick-off, they waited until the deadline before confirming the 25-year-old Farrell's place in the No 12 shirt.
Should Farrell be unable to kick during the match, England do have alternative options in fly-half George Ford and wing Elliot Daly, a long-range specialist.
However, the previous occasion Ford was England's goal-kicker, against Wales at Twickenham in May last year, he missed six kicks out of seven.
If England beat Scotland on Saturday they will equal New Zealand's record of 18 consecutive Test wins by a tier one nation and will also retain the Six Nations title they won with a Grand Slam last year.
