Former England and British & Irish Lions coach Phil Larder is to rejoin Worcester Warriors as defence coach.
The 66-year-old was part of Clive Woodward's backroom staff when England won the Rugby World Cup in 2003.
He previously worked with the Warriors in their 2006/07 Premiership season and will take up his role ahead of their return to the top flight.
"They are an exciting club with tremendous modern facilities and excellent potential," said Larder.
"Last year, under the guidance of head coach Richard Hill, they developed a winning habit and secured promotion.
"My job is not only to help the Warriors cement a place in the Premiership but help to inspire them to become one of the leading rugby clubs in England."
Hill added: "Defence is very important; we perhaps didn't put too much emphasis on it last year and it was more about the attack.
"As the importance grows during the Premiership, getting a specialist into the team like Phil gives the players so much confidence.
"Phil is one of the best in his field and comes with a very good reputation."
Larder has extensive experience in both rugby union and rugby league and worked with Leicester Tigers for four years, helping them to back-to-back Heineken Cup victories in 2001 and 2002.
Meanwhile, the Warriors have appointed nutritionist Adam Carey on a new two-year contract.
Carey was also part of the England backroom staff for 2003 World Cup success.
Warriors general manager Charlie Little said: "It's always good to have specialists who have worked at the very top level to come and work with us.
"This is a big step forward for the club by employing Phil and Adam, this really makes a statement.
"A coaching team of Richard Hill, Phil Davies and Phil Larder is pretty impressive and the excitement at the club is building as we work towards the Premiership season."
