Scotland lock Scott MacLeod is set to quit the international stage after revealing he will move to Japan.
The 32-year-old has been capped 24 times but he has now rejected an offer from the Scottish Rugby Union to join Kobe Steelers when his current deal expires in the summer.
As a result the former Borders and Scarlets forward will be unable for international selection when he completes his switch.
MacLeod said: "I've thoroughly enjoyed my two-and-a-bit years with Edinburgh, and I'll take away a lot of happy memories of things we've achieved on the field, and of the people that I've encountered.
"There's a great camaraderie at the club, and it's a wonderful feeling to play and work beside guys that are friends as well as colleagues.
"I'd like to thank my team-mates, and the Edinburgh coaches and staff, for all the support they've given me and I look forward to staying in touch with them when I leave the club.
"It's been a very difficult decision to make, because Edinburgh are close to my heart and I've a lot of affection for the club, but the opportunity to go to Japan is exciting not just for me, but for my family. From a lifestyle and learning perspective, this will be great for us all.
"After the recent tragic events in Japan, I've been in regular contact with the Steelers, because clearly I would never do anything to expose my family to risk.
"I have a huge amount of sympathy for those who've suffered terrible losses, but I've been given the appropriate reassurances and as a family we're entirely comfortable about going out there.
"My focus remains on helping Edinburgh finish the Magners League regular season strongly, after which I will be throwing myself into this new challenge."
Scotland head coach Andy Robinson added: "Scott's an honest person and he's sat down with me to detail his reasons for making himself unavailable for selection.
"I respect his decision and will be happy to talk to him if that situation changes."
