Edinburgh have confirmed that Izak van der Westhuizen is to join the club from the Cheetahs at the end of the Currie Cup season.
The 26-year-old lock, who was capped by South Africa at Under-18s level, has started all 12 of the Cheetahs' games in this season's Super Rugby.
However he has now agreed to join Edinburgh on a two-year deal.
Van der Westhuizen told the club's official site: "I want to test myself against the top players in Europe so when I found out Edinburgh Rugby were looking for a player with my skill-set, I was desperate to sign.
"I like the pace the boys play with, it's very similar to a Super Rugby style which gives me a lot of confidence that I'll fit in well.
"I run the set-piece for the Cheetahs but, when the ball's in play, I like to be in the centre of the park getting stuck into the physical side of the game and hitting rucks.
"I'm really looking forward to joining the club. They've some real talent joining the squad and some quality Scottish players re-signed too so I think it's the ideal time to be part of a really exciting squad."
