The Bromley winger, who signed from Chesterfield in December, has accepted his professional career is over.
Hines, who has also played for West Ham, Dagenham and Maidstone, has acted on medical advice and confirmed his retirement.
He took to social media to make the devastating announcement and said: “The past few weeks have been the toughest of my career. I’ve had to make one of the hardest decisions in my life and even now as I write this message I’m in tears.
“But after getting medical advice and with a broken heart, I’m going to retire from professional football immediately. Mentally and emotionally this is difficult for me but I had a choice to make.”
Bromley boss Neil Smith, his final manager of his 13-year career, told the club’s website: “I’m absolutely devastated for Zavon.
“When he’s played against us he’s been exceptional and he was someone I couldn’t wait to get into the club. To then hear the sad news was gutting.
“He will be a massive loss to the squad. Since he’s walked through the door he has committed to the squad and to me. I’d just like to think he has a future in the game as a coach, which I believe he has.
“As a club we will and as a manager and as a person I will help him through this difficult time.”
