The 36 year-old defeated ‘Money Team’ member Ashley Theophane to claim the British super lightweight crown at the height of his career in 2012, but has found it difficult to get the backing since losing his belt to Curtis Woodhouse in his fourth defence last year.
“Today I announce my retirement as a professional fighter,” said Hamilton.
“I can’t get the right deal, but I’ve got nothing bad to say about the sport as it has changed my life and has given me a remarkable story.
“I will still go to schools and tell how I defeated the odds and became a champion, but I’m now a professional trainer working with Barry Smith’s stable of fighters. (The likes of) Deon (supernatural) Reid, Tommy (Gun) Martin, ‘Big Bad’ Brad Smith and Biola ‘Killer’ Kudus.”
Hamilton, who is also known for his rapping ability, scored victories over Dave Ryan, Peter McDonough, Stevie Williams and John Watson in a ring stint that began later than most at the age of 28 back in 2006 and WBN wishes him well for the future.
