Stormers and Springbok lock Eben Etzebeth will join Toulon after the 2019 World Cup on a two-year deal.
This was confirmed on Thursday by club president Mourad Boudjellal, who said Etzebeth had finalised an agreement earlier this week.
The three-time European champions, who are currently 10th on the French Top 14 log, have also signed Nehe-Milner Skudder on a three-year deal.
The All Blacks wing will join the club next June ahead of the 2019-20 European season.
