England have welcomed back Lions duo Manu Tuilagi and Luke Cowan-Dickie ahead of the Calcutta Cup match with Scotland next weekend.
The duo, along with forward George Martin, return to Steve Borthwick's side having missed the opening two rounds of the Six Nations.
Tuilagi has been out since December because of a groin injury, but has replaced uncapped Harlequins centre Oscar Beard in the 36-man squad.
Northampton centre Fraser Dingwall, who opted to play for England at Test level while also qualifying for Scotland, lined up in the midfield alongside Henry Slade for the victories against Italy and Wales but neither has Tuilagi’s ability to carry England over the gainline.
Borthwick will hope to have the 32-year-old, whose career has been blighted by a series of injuries, available for the trip to Edinburgh
Cowan-Dickie, who was sent to the sin-bin and conceded a penalty try the last time England visited Scottish Gas Murrayfield, returns having been forced to withdraw from the original squad due to an undisclosed medical issue.
His availability at hooker will relieve the pressure on captain Jamie George, whose workload has been increased by the lack of experienced alternatives in the position.
Leicester forward Martin, who was a key part of England's World Cup campaign, is back from a knee problem. He can play either at lock or in the back-row, and replaces Northampton's Tom Pearson in Borthwick’s reshaped squad.
Meanwhile, Marcus Smith and Ollie Lawrence will join the squad as they continue their rehabilitation from injuries.
Lawrence, a club colleague of Finn Russell and Cameron Redpath at Bath, faces a battle to prove his fitness with the centre continuing to rehab his hip problem in camp.
Harlequins fly-half Smith has a calf problem, which has kept him out of the opening two matches, with Northampton's Fin Smith - another who could have represented Scotland - making his debut against Italy, but unused in the win over Wales.
