South Africa international Gio Aplon will join Top 14 side Grenoble on a two-year deal at the end of the Super Rugby season.
The 31-year-old, who can play at wing or full-back, has won 17 caps for the Springboks and scored five tries.
Aplon arrives in France from the Stormers, where has played 80 Super Rugby games and scored 17 tries.
Stormers head coach Allister Coetzee said: "Gio has been a loyal servant of WP Rugby and a true son of DHL Newlands. He will be missed, but he goes with our blessing.
"At almost 32 years of age, having just got married and starting a young family, we were never going to stand in Gio's way when he asked to be released - having first played in the Blue and White hoops (as a Vodacom Cup player) back in 2005."
Aplon becomes Grenoble's sixth recruit for next season after South African scrum-half Charl McLeod (Sharks), French fly-half Jonathan Wisniewski (Racing-Metro), prop Remy Hugues (Dax), New Zealand back Jackson Willison (Auckland Blues) and prop Julien Brugnaut (Racing-Metro).
The team are currently 10th in Top 14 but within seven points of sixth-placed Toulouse and a place in the playoffs.
Former Ireland and Leinster hooker Bernard Jackman is defence coach at Grenoble, but he will take over as head coach from next season.
