Manu Tuilagi has been left out of an England training squad for the Six Nations as he makes his latest comeback from injury.
Tuilagi has not played for England since March of last year and has been hampered by a number of fitness problems.
The centre recently made his Leicester Tigers return from knee surgery and claimed that his issues are over following a visit to a witch doctor in Samoa, the country of his birth.
But he does not yet appear to be in England coach Eddie Jones' plans, though Billy Vunipola and James Haskell have been recalled to the 34-man party.
Saracens number eight Vunipola missed the November internationals with a knee injury and Wasps flanker Haskell was left out of Jones' squad for those Tests.
"This camp in Brighton is important for us to set the tone as a squad ahead of the Six Nations," said Jones.
"We will need to improve if we are to hunt down our opponents and beat them. This tournament will be exciting and challenging, as we know we will play against some very strong teams.
"Brighton will provide a great base to begin our preparations with players coming away with a clear plan for our opening match of the campaign against Italy."
England are seeking a third successive Six Nations title, having narrowly missed out on consecutive Grand Slams this year.

Backs: Mike Brown (Harlequins), Nathan Earle (Saracens), Jonny May (Leicester Tigers), Denny Solomona (Sale Sharks), Anthony Watson (Bath Rugby), Danny Care (Harlequins), Owen Farrell (Saracens), George Ford (Leicester Tigers), Piers Francis (Northampton Saints), Jonathan Joseph (Bath Rugby), Jack Nowell (Exeter Chiefs), Henry Slade (Exeter Chiefs), Ben Te'o (Worcester Warriors), Marcus Smith (Harlequins), Ben Youngs (Leicester Tigers).
