Now he will play in the south of France with a club that will play in France's Pro2 next season, though he remains fully committed to extending his Scotland career.
Blair said: "I've never made a secret of my desire to play in France at some stage during my career and I'm delighted that it will be with Brive.
"It's a lovely place with an incredible support and I'm really looking forward to meeting up with them after the Scotland tour.
"There were a number of considerations that I wanted to take into account for me and my family and Brive ticks a lot of the boxes that matter to us."
