A World Cup-winning Springbok lock will join Gloucester ahead of the 2026-27 season.

The English Premiership club has signed Jean Kleyn, who’s made 160 appearances for Munster over the past 10 seasons.

A powerful and uncompromising presence in the engine room, Kleyn brings a wealth of experience at the highest level of the game, representing both Ireland and the Springboks, winning the 2023 World Cup with the latter.

Renowned for his physicality, work rate and leadership, the 2.03m, 32-year-old adds significant quality and depth to Gloucester’s forward pack.

“Jean is a player I’ve admired for a long time,” said director of rugby George Skivington. “He brings real edge, experience, and a winning mentality, which will be invaluable for our group.

“His physical presence and professionalism will raise standards across the squad, and we’re excited to welcome him to Kingsholm.”

“I’m thrilled to be joining Gloucester next season,” Kleyn said. “It’s a club with incredible history and a passionate fan base, and the vision shared with me really matched what I was looking for in the next chapter of my career. I can’t wait to get started, meet the supporters, and give everything I have for this team.”
