Edinburgh lock Izak van der Westhuizen has joined his new team-mates after arriving from South Africa.
The 26-year-old, who signed a two-year deal with the Pro12 club in May, arrives following Free State Cheetahs' Currie Cup campaign.
Second-row Van der Westhuizen started every Super Rugby and Currie Cup match for the Cheetahs this season.
"I've played a lot of rugby this season but I'm keen to get into action as soon as possible," he said.
Van der Westhuizen is the third southern-hemisphere signing for Edinburgh this season, following fellow Cheetahs prop Willem Nel and former Highlanders centre Ben Atiga.
"It's often said that the Pro12 and Heineken Cup are the most physical competitions in the world, so I'm looking forward to seeing how it compares with my experiences in the southern hemisphere," added the new arrival.
"I consider myself a pretty physical player, particularly in the tackle and contact areas, clearing out rucks and so on, while my lineout work is also something I pride myself on."
Van der Westhuizen is expected to be available for selection for Friday's match against Ulster at Ravenhill subject to a medical.
