Anton Bresler will join Edinburgh on a three-year deal at the end of the Super Rugby season.
The Namibian-born lock started the opening five matches for the Sharks this year before injuring his shoulder against the Bulls in March. He is expected to return to Super Rugby this weekend.
'When I first heard there was interest from Edinburgh and [head coach] Alan Solomons, I immediately did some research to build up my knowledge of the country and the club,' said Bresler. 'I read about some big wins and some narrow losses against some of the top teams in the competitions and it struck me as a chance to join a club that's moving in the right direction and where hopefully, together, we'll be able to push on and do some great things.
'Anton is a player who, despite being just 26, has been a regular in the Sharks starting line-up for the past three to four years,' said Solomons. 'He is a big, powerful and abrasive player. He's a front of the lineout jumper and I would describe him as more of an enforcer lock.'
Solomons has already brought several South Africans to the club, including Andries Strauss, Carl Bezuidenhout, Wicus Blaauw and Cornell du Preez.
