Toulon winger David Smith will join Castres next season after signing a four-year deal with the Top 14 side.
Smith has been with Toulon since 2011, and finished this season as the top try-scorer in the Top 14 with 16 tries.
However he remained second choice for the big games, with Bryan Habana, Drew Mitchell and Delon Armitage all ahead of him in the pecking order, and Josua Tuisova in the process of overtaking him.
As a result, Smith will head to Castres, who narrowly avoided relegation this season but have since recruited ambitiously, with the likes of another former Toulon player, Rudi Wulf, and Oyonnax duo Antoine Tichit and Benjamin Urdapilleta, also joining.
"I chose Castres because it's a fantastic club and I wanted something new in my life," said Smith.
"It's a beautiful city with a great team and I'm very excited to where the blue and white jersey next season.
"I will do my best for the next four years and I'm very pleased to have chosen Castres. I can't wait to meet the squad, it seems like there is a family feel here and I hope I will get on well with everybody."
