33 players have been named by England sevens coach Mike Friday for the 2006/07 season.
The players will train with the 11 core squad players but will only be available for four of the eight IRB Sevens events.
Worcester's new signing Marcel Garvey features alongside Dom Shabbo of London Irish.
The squad will meet for three training sessions before their first tournament, the Dubai Sevens in December.
