The 26-year-old is one of the first major signings for the Isuzu Southern Kings, who are implementing an ambitious recruitment strategy ahead of the new Guinness PRO14 season.
The second-row talent, who will add firepower to the South African forward pack, will draw intrigue when he squares up for the first time against his older brother – the reigning World Rugby Player of the Year has been in stellar form for the reigning Guinness PRO14 Champions this season.
Sexton, currently the captain of English Championship side Jersey Reds and regarded as one of the top performers in the league, is keen to push on at his new club.
“This is an exciting period in my career,” he said.
“I have been following the Isuzu Southern Kings, particularly in the Guinness PRO14, and I am looking forward to be part of the team, the culture and the exciting new era that lies ahead for the franchise.
“I am grateful for the years spent at Jersey Reds and the role the club played in the growth of my career. I look forward to further growth and making a positive contribution at the Isuzu Southern Kings.”
Isuzu Southern Kings’ Director of High Performance Robbi Kempson said: “It is part of our ambitious plan to bring quality players to assist us reach our goal of becoming a world-class side, and the inclusion of individuals like Jerry will bolster this process.”
Sexton has been an ever-present feature in the Jersey Reds’ league XV, starting all 43 Championship games since moving to Jersey two years ago.
Captaining the side in the majority of the the time he has been at the club, he’s also chipped in with eight tries of his own.
Jersey Reds Director of Rugby Harvey Biljon added: “Jerry has contributed a huge amount during his time in Jersey and to see another player get the opportunity to play at the next level is very rewarding for the coaches and should also motivate the players to continue to work towards reaching their own goals.
“We will all enjoy watching Jerry play in the Guinness PRO14 and potentially even see the ‘Sexton v Sexton’ match-up. I trust he will enjoy South Africa but we hope that we’ll see Jerry in Jersey again in the future.”
His inclusion in the Isuzu Southern Kings squad follows that of utility back Courtney Winnaar, who signed for the side a fortnight ago.
