Campbell had previously agreed to play on in season 2012 but has opted to hang up the boots at the end of this year, closing the curtain on a stellar 14-year career in which he has played more than 260 NRL matches, won a premiership, Dally M Medal, Paul Broughton Medal and Ken Stephen Medal.
The 34-year-old, who made his first grade debut for the Gold Coast Chargers in 1998, said he had made the difficult decision to retire because he wanted to focus on his community work and life after football.
“I feel like it’s time for me to start the next phase of my life off the field,’’ said Campbell.
“I could have gone another year but I want to concentrate more on what I’m going to be doing after footy here at the Titans and as a Learn Earn Legend! ambassador.
“I’m still going to be employed by the club off the field and I’ll still be around to help some of the new guys settle in next year.’’
