Moriarty also leaving Gloucester
Gloucester have announced that defence coach Paul Moriarty is to leave the club - 24 hours after they revealed the departure of rugby director Nigel Davies.
Former Wales back-row forward Moriarty will not have his contract renewed, the Aviva Premiership club said.
He was one of Davies' first appointments in July 2012 as they resumed a coaching partnership that saw them work together at the Llanelli-based Scarlets.
" Firstly, I would like to thank Paul for all his efforts over the past two seasons," Gloucester chief executive Stephen Vaughan said.
" He has worked incredibly hard at the role. No-one can fault his application and dedication.
"However, defence is one of the most important facets of the modern game and we plan to introduce a new approach and philosophy in that area.
"Accordingly, we feel that with a new director of rugby being sought, it's only right and proper that we allow that individual to have a say in the recruitment of new coaches.
"Paul is now out of contract, and we have informed him that his contract will not be renewed.
"He is naturally disappointed, but understands the rationale. We would like to wish him well for the future."
Newport Gwent Dragons coaches Lyn Jones and Kingsley Jones, meanwhile, are thought to be in the frame for a joint switch to Gloucester.
Former London Welsh boss Lyn Jones and ex-Gloucester captain Kingsley Jones could head up a new-look coaching team at Kingsholm next season, Press Association Sport understands.
Former All Blacks coach Wayne Smith is also understood to have an interest in replacing Davies, who was unseated on Monday after two years in the west country.
