England sevens coach Mike Friday, who captained England at the last Rugby World Cup Sevens in Argentina in 2001, said: "To cut the squad from 15 to 12 was incredibly hard but I am confident that the 12 who have been selected are the strongest possible squad for this tournament.
"I am fortunate to be in the situation whereby all 15 players could have performed well and the three players who have not been selected on this occasion are all very talented sevens players.
"I am particularly pleased for Neil Starling of Northampton Saints as he is perhaps the wildcard of the squad - having progressed incredibly quickly from the Saints Academy to the England Sevens World Cup squad this season. He played well at the weekend against Gloucester and I am sure he will step up to the plate this weekend. It will be a fantastic experience for him."
Friday added: "The squad will be captained by Simon Amor (Gloucester) and includes many talented and experienced sevens players such as Ben Gollings, Pat Sanderson (Worcester Warriors) and Henry Paul (Gloucester).
"The squad also includes what I believe to be the next generation of England XVs players, who are also impressive sevens players, including Peter Richards (London Wasps), Ugo Monye (NEC Harlequins) and Richard Haughton (Saracens).
"The three players who have not been selected on this occasion still have plenty of opportunities ahead of them within the England Sevens squad, not only this season but with the Commonwealth Games which are held in Australia next March."
Mathew Tait (Newcastle Falcons) was withdrawn from the squad on Friday due to injury. Friday said, "All of the squad are disappointed that Mathew couldn't be with us, but we wish him well with his recovery from his injury and hope he is able to return to the England Sevens set up in the near future."
