Orie is set to play for them in the Guinness PRO14 for the next two months before returning to take up his regular role for his Vodacom Super Rugby franchise, the Emirates Lions.
The big lock, who represented the Springboks in the Castle Lager Rugby Championship, is currently on standby for the Bok squad after narrowly missing out on selection for the Rugby World Cup and is excited about the prospect of playing in the Guinness PRO14.
“I am looking forward to joining a great club like Ospreys. There are a few big fixtures coming up for the club and hopefully I can be part and contribute,” he said.
“While watching some of their recent games I am impressed with the character of the team to pull off a couple of close wins.
“I believe I will also learn a lot playing in a different league and different conditions from what I am used to which makes this couple of months with Ospreys even more exciting.”
Orie is waiting for his visa before heading north to a club that already has three South African familiar faces in Tom Botha, Hanno Dircksen and Shaun Venter playing for them.
