“Josh has long been at the heart of the Bulldogs,” said Bulldogs Rugby League Football Club chairman John Khoury.
“He has led this great club with pride. He has bled blue and white and played for his state and for his country.
“We know this decision has not been an easy one, and while it is a sad day, there is no doubt that despite not lacing up the boots and running out in 2023, he will continue to inspire the Bulldogs team and our community for many more years to come.
“We cannot thank him enough for everything he has done for our club, but now it is time to reflect on and celebrate his wonderful career.”
Jackson’s departure will free up plenty of cash for 2023 as the Bulldogs look to continue their rebuild under incoming coach Cameron Ciraldo.
The club is desperate to re-sign Matt Burton on a long-term deal, while they are also searching for another star recruit to help them return to the finals for the first time since 2016.
The Bulldogs will be far more competitive next season, with Reed Mahoney and Viliame Kikau joining the club, but they will need to fill the massive leadership void caused by Jackson’s exit.
“Josh has always epitomised what this club is about,” Bulldogs assistant coach Mick Potter said after leading Jackson as the club’s interim coach for much of 2022.
“He’s tough. He’s resilient. He leaves everything on the footy field.
“He is and always will be the epitome of a Bulldog.
“His efforts and professionalism are unparalleled, and it will be hard to fill that void in the team.
“Josh’s actions have always been about doing the best for the team and the club, and that is what he has done.”
