Huw Evans has resigned from his position as director of Gloucester, giving "differences of opinion" with the chairman and board as his reason for his departure from the club, reports BBC Sport.
Evans - who was in the role for a little over 12 months - didn't support the decisions to sack former director of rugby Nigel Davies or to release World Cup winning centre Mike Tindall.
The former Scarlets chairman announced his decision in a statement, which read: "I wholeheartedly want to see the club succeed, and now outside board level, I will continue to support in every way I can.
"Unfortunately I had fundamental differences of opinion on the rugby vision and culture held at board level which means I cannot continue."
One of the main reasons for Evans decision, which adds to the instability in the Gloucester backroom that has plagued their campaigns of late, was Davies' sacking back in May.
Davies led the club to fifth place during his first season at Kingsholm, but after they finished ninth last term, he was relived of his duties.
The new regime at Gloucester also meant Tindall was not offered a new contract, forcing the 2003 World Cup star to retire - which disappointed Evans who said: "I have huge respect for Nigel Davies' vision, rugby intellect and capability and the strategic plan which he'd put together which was said to be backed by the board.
"There is no doubt in my mind that Nigel would have succeeded and handsomely at that.
"To me Mike Tindall typified the strong, traditional Gloucester ethos of honesty, courage and endeavour, a world class warrior.
"His experience and passion for Kingsholm and all that Gloucester stands for should have been retained."
However, despite Evans walking away from the club, new director of rugby David Humphreys hailed the recruitment they have made during the summer and insisted they have huge potential going into the new season.
He told BBC Points West: "Huge credit to Nigel and [chief executive] Steve Vaughan in terms of the squad that they've put together.
"I think when you look at the players that have been brought in, the Gloucester squad now is a squad with huge potential and some top quality international players."
Gloucester kick off their Aviva Premiership campaign with a trip to Northampton on September 5.
