A former England U20 cap, he has amassed considerable first team experience over the past few seasons, and earned selection for the England Saxons.

A one club man, Gloucester supporters will be pleased to see him extend his stay at Kingsholm whilst also wondering why he only has ten caps for England.

Director of Rugby Nigel Davies confirmed that the five players agreeing new deals is very positive news for the club, and that recruitment for 2013-14 is coming along nicely.
"I'm delighted that all four of them have committed their futures to Gloucester Rugby. Charlie, Darren, James and Shaun have been a big part of the club's success in recent years and Elliott has a huge future in front of him.
"It's been a busy couple of months for us on top of the re-signings announced before Christmas and the arrivals next season of John Afoa and Richard Hibbard.
"The players can see where the club is heading, and are excited to be a part of that going forward. Their commitment speaks volumes.
"And, once again, it's a testimony to the hard work and commitment of everyone at the club. We're able to invest significantly in our team thanks to the backing of our board, the continued financial success of Gloucester Rugby and the significant investment made by our partners, sponsors and supporters."
