London Welsh have parted company with head coach Lyn Jones after he asked to be released from the third and final year of his contract.
Jones' request was for personal reasons and reflected a desire to move back to Wales to be nearer his family and home.
"It's been an unbelievable journey with London Welsh, but sadly, and I do sincerely mean sadly, it now personally draws to a close," said Jones, who had been linked to a move to the Dragons.
"Just when I thought, as a coach, I'd experienced all what the game can offer, London Welsh happened.
"The last two years have proved both exhilarating and challenging in Richmond, but my return to Wales has to happen and I leave with hope that I have helped players improve in a small way."
Chairman Bleddyn Phillips added: "We are very sad to lose Lyn but after several meetings with him over the past week or so it is abundantly clear that he wishes to move back to Wales for very understandable personal reasons and to be closer to his family.
"We are very fortunate to have had someone of Lyn's calibre as our head coach these past two seasons and, as a Club, owe him an enormous debt of gratitude for all that he has achieved for London Welsh.
"I know that the players and fellow members of the coaching staff will equally miss his utter dedication and commitment to the Club coupled with his professionalism and strive for excellence across all elements of the game.
"The club is well under way in the process of choosing a successor to Lyn and has already identified a short list of three eminently qualified people to take over the role of head coach."
