Cape Town - Lions loose forward Ruan Ackermann will join his father Johan at Gloucester.
The English club confirmed on their website that he will join the team subject to visa clearance.
Ackermann, 21, represented South Africa 'A' in their two-match series with the French Barbarians, ahead of the culmination of the Super Rugby season.
Following speculation, Gloucester confirmed the loose forward's addition to the squad following the end of the Lions' involvement in the southern hemisphere competition.
The Lions lost 25-17 to the Crusaders in the Super Rugby final at Ellis Park.
Ackermann made his first appearance for the Golden Lions in 2015, before being included in the Lions' Super Rugby squad for the 2016 season.
Gloucester director of rugby David Humphreys spoke of his excitement to see one of South Africa's most promising talents develop in the Premiership in Cherry and White.
"We are pleased that we have been able to bring Ruan on board, and he will definitely complement our existing resources in the loose trio, an area where we have real strength in depth and competition for places," Humphreys told the club's website.
"Johan of course knows all about the qualities that Ruan possesses, and Ruan himself knows exactly the high standards that Johan expects of his team and his players.
"Ruan has proved time and time again in Super Rugby this season how capable a player he is, taking on and matching some quality performers, and has also demonstrated his versatility in playing across the loose trio."
