England boss Stuart Lancaster has named a 32-man group for training at Loughborough University this week.
It includes all 22 players involved in Saturday's gripping RBS 6 Nations clash against Wales at Twickenham, which was won 19-12 by the visitors.
Saracens fly-half Charlie Hodgson, who missed the Wales clash because of a finger injury, also features, as does Stade Francais lock Tom Palmer.
Palmer was dropped for the Wales game and replaced by Leicester's Geoff Parling, who was among three players who made their first Six Nations starts.
The squad will meet up tonight through to Thursday afternoon as interim head coach Lancaster begins preparations for England's Six Nations clash against France in Paris on March 11.
A selection of players will be released on Wednesday evening to train with their clubs ahead of next weekend's Aviva Premiership action.
