David Wiese is the latest player to have effectively called time on his South Africa career by signing a Kolpak deal with Sussex.
The 31-year-old all-rounder has agreed a three-year contract with the county where he spent two spells as an overseas player last year.
Wiese had been named in the Proteas squad for the three-match Twenty20 series against Sri Lanka this month, but was withdrawn after revealing he was bound for England.
South Africa were rocked by Kyle Abbott and Rilee Rossouw's decisions to take up Kolpak deals last week, with Stiaan van Zyl, Simon Harmer and Hardus Viljoen having already gone down the same route.
Wiese said: "I am very excited to be joining Sussex on a long-term deal. I thoroughly enjoyed my stint with the club last year and it made my decision so much easier when offered to return.
"Sussex is an extremely ambitious club and I look forward to being part of their future.
"I would like to thank Cricket South Africa for giving me the opportunity of fulfilling my lifelong dream of representing my country in the sport I love."
Wiese made 20 appearances for his country in the shortest format, taking 24 wickets at an average of 20.70. He also played in six one-day internationals, the last of which came against England last year.
Proteas captain Faf du Plessis last week described Abbott's Kolpak deal as a "red flag" which must be addressed.
