Scotland centre Mark Bennett is to join Edinburgh from domestic rivals Glasgow at the end of the season, it was announced Tuesday.
Bennett, 24, leaves after Glasgow chiefs secured the services of fellow Scotland midfielder Huw Jones from South African side the Stormers.
Meanwhile back-row Josh Strauss and prop Gordon Reid are also set to leave Glasgow.
The shake-up comes amid coaching changes that will see Glasgow boss Gregor Townsend leave at the end of the current campaign to become Scotland coach, with Kiwi Dave Rennie taking over at the Warriors.
Bennett, nominated for World Rugby's breakthrough players of the year award after the 2015 World Cup, has so far made 64 appearances for Glasgow, scoring 20 tries, in two spells separated by a short stint with French Top 14 side Clermont.
An Olympic silver medallist with the Great Britain sevens' team at last year's Games in Rio, will join Edinburgh on a three-year deal.
"A key factor in my decision was that there's a young squad at Edinburgh, who are going in the right direction and I can feel like I can add to that," said Bennett.
"At 24 I think I could be one of the older boys in the Edinburgh backline, which would be a new experience for me, but one that I'm looking forward to next season."
Acting Edinburgh head coach Duncan Hodge added: "Mark is a phenomenal player, who has accomplished a lot both at club and international level at the age of just 24, and his experience will be a welcome addition to our backline."
Meanwhile Townsend, set to work again with the departing Glasgow trio as Scotland coach, said: "Although there is a lot of rugby still to be played this season, I'd like to acknowledge and thank Gordy, Josh and Mark's invaluable contributions since they joined the club."
