Ospreys have signed South African lock Rynier Bernardo on a three-year contract.
Bernando, 22, will move from Eastern Province Kings and become the club's fourth signing for next season following Josh Matavesi from Worcester and Dragons duo Dan Evans and Sam Parry.
"This is a fantastic opportunity for me, personally and professionally, and I'm really excited about arriving in Wales this summer," Bernardo told the Ospreys' official website.
"The Ospreys are a great team used to competing at the top end of the PRO12, with some great players, and I'm looking forward to being a part of a young and talented squad there.
"It's a big challenge for me, but I can't wait to get started. Hopefully I'll be able to make a big impression and help the team to more success, domestically and in European competition."
Rugby operations manager Andy Lloyd is hoping Bernardo will add some muscle to the Ospreys pack.
"He is highly respected in his home country and comes with a strong reputation as a traditional second-row who tackles well, hits rucks, and has the all-round physical edge that you expect from a South African in that position," said Lloyd.
"He's a young man who has chosen to come here for the challenge instead of staying in South Africa where our feedback tells us he is extremely highly regarded as a potential future Springbok."
