Former British and Commonwealth champion Chris Jenkins says he is retiring from boxing because of the results of his annual brain scan.
The Welshman says his scan shows “an abnormality,” compared with last year.
The 35-year old says he is retiring as he wants to prioritise his health.
“This is definitely the hardest thing I’ve ever had to write,” he wrote in a social media post. “I have no option but to retire from the sport I’ve competed in since the age of 12.”
Jenkins made the decision after a conversation with his trainer, former world-title challenger Gary Lockett.
“I recently had the yearly routine brain scan, it’s shown some abnormality from last year’s scan meaning I’d be putting myself at risk if I was to continue boxing,” he wrote.
“A hard fight or hard spar could result in greater risk of having early dementia or Parkinson’s.
“Having a young family, this is a risk I can’t even contemplate taking. I need to be there and provide for my family.
“It still hasn’t sunk in as of yet.”
Jenkins, 35, who made his professional debut in 2012 in his home city of Swansea, fought 33 times a professional, retiring with a record of 23 wins, seven defeats and three draws.
Jenkins won a light-welterweight version of Prizefighter in 2013, six years before he would win British and Commonwealth titles at welterweight, holding the titles until 2021.
Lockett says Jenkins is a throwback fighter who gave everything he had to the sport.
“There aren’t many around like Chris anymore,” Lockett told BBC Sport Wales.
“He became my fourth British champion and him winning the title against Johnny Garton in 2019 was one of the best nights of my coaching career.
“He’s such a great fella and to win the title, he was in tears, it was just a fantastic night that lives long in the memory.
“We’ve had some fantastic times and he is an absolutely lovely guy. He’s a real family man with a lovely wife and three beautiful children who will support him.
“He is someone you would always want in your corner in any tough situation. He is a special person.”
