Barely a week after head coach Andy Robinson left his post following eight defeats in nine Tests, Reddin has also departed Twickenham.

And the 37-year-old has expressed his disappointment at the decision.

Reddin spent eight years working with England teams, and he oversaw the conditioning and fitness regime of the World Cup-winning side three years ago.

Reddin's work - he was the Rugby Football Unions head of fitness and nutrition - will be taken up by RFU national fitness coach Calvin Morris.

It means that in less than eight months, Robinson, Reddin, ex-defence coach Phil Larder, former backs coach Joe Lydon and kicking guru Dave Alred have all left the RFU.

Reddin, an acclaimed leader in his specialised field of work, said: Although the RFU have explained the rationale for their decision to make my role redundant, I am disappointed to be leaving.

"It has been a great privilege to have been involved with England over the past eight years and almost 100 test matches. I have worked with some absolutely incredible players and two outstanding coaches in Clive Woodward and Andy Robinson.

"I do feel proud to have been associated with the most successful period in English rugby history and my hope in leaving is that positive changes are made to recreate that."

RFU Elite Rugby Director Rob Andrew paid tribute to Reddin's contribution to England Rugby.

Andrew said: "Dave Reddin made a huge impact during his eight years with the RFU in developing a world class fitness programme to support the senior side.

"His work ensured that England arrived at the 2003 Rugby World Cup in peak condition and he was a major reason behind the team's success at that tournament.

"Dave goes with our thanks and best wishes for the future and I'm sure that he will continue to make a major contribution to elite sport in this country."
