Saracens defence coach Paul Gustard will join the England coaching team for this summer's tour to Argentina.
Gustard follows in the footsteps of former Men in Blacks coach Andy Farrell who left Sarries to link up with England permanently in 2012.
Farrell though, together with Graham Rowntree, will be unavailable due to coaching commitments with the British and Irish Lions tour to Australia.
Gustard will join the national side in June along with Exeter Chiefs director of rugby Rob Baxter
The Sarries forward told the RFU: “It's obviously a great honour to be asked to assist in the preparation of the England squad and only once Saracens' involvement in the Premiership and the Heineken Cup has ended.
"I am grateful to Saracens for giving me the opportunity to continue my development as a coach at national level."
England head coach Stuart Lancaster added: “We are delighted to have two quality coaches who have come through the English system for what will be a hugely significant tour for us and a big thank you should go to Saracens, Exeter and Aviva Premiership Rugby for supporting England in this way.
“It was important that we found two coaches who could mirror the skill set of Graham and Andy and come in and keep developing the players within our system.
“Paul, having worked together with Andy at Saracens already has a good understanding of how we operate and Rob, who has done a great job in developing a very competitive Exeter pack, will pick up the set piece and breakdown.
"Both will work alongside Mike as part of our integrated coaching team.
“We are looking forward to both coaches joining us after their club commitments finish on what is an important tour in our development as a team.”
