The Leith-raised Buchanan became the undisputed lightweight world champion in 1971 after defeating Ruben Navarro at the Sports Arena in Los Angeles.
A statement issued by his son Mark Buchanan revealed that his father “has good days and bad days” in his care home, but expects the 76-year-old to be at the statue ceremony in the capital in August.
The statement read: “In addition to some news reports in September 2021, I am reporting that my father Ken Buchanan MBE has a formal diagnosis of dementia.
“My father resides in a private residence in Edinburgh, where he is well looked after.
“Lately, several sports stars have announced their dementia and at the age of 76, my father’s dementia probably similarly occurred as a result of his sport.
“The result of my father’s dementia leaves him very forgetful at times.
“My father has good days and bad days, as those familiar with dementia will know.
“My father’s attorney and I had to make the difficult decision to place my father in a private care home for his own safety due to his increasing vulnerability.
“My father’s care is excellent and he enjoys visits from family and friends.
“Unfortunately, we have had to make the difficult decision to prevent certain people who were having a negative impact on my father from visiting the private care home, this was not an easy decision, however, my father’s well-being is of paramount importance. for us.
“My father’s fame lives on throughout the boxing world. We received on behalf of my father an invitation for him to be inducted into the US West Coast Boxing Hall of Fame. Due to his cognitive impairment, we have had to decline this invitation.
“My father’s public appearances are likely to be limited now. We always hope that my father will be able to attend his charter inauguration which will probably be in August 2022.
“My father’s legacy has been passed down to many great Scottish boxers since the 1970s and I hope that my father’s World Championship victories in the USA will continue to inspire young Scottish boxers to be great champions.”
Buchanan has been inducted into the International Boxing Hall of Fame.
Last year, in a documentary of his remarkable career, he said he has lived a “great life”.
In “Undisputed: The Life and Times of Ken Buchanan,” originally shown on BBC Scotland, the ring legend studies vintage photographs of his life and career.
She recalls moments of pride, from teaching playground bullies to the “magic” of representing Scotland, as well as the great tragedies of her life, including the death of her most passionate supporter, her mother Cathy, at the age of just 51, and ring legend Roberto Duran’s disgusting cheap shot that cost him his world title.
He said: “I’ve had my life and I’ve had a good kick of the ball, and I don’t have axes to grind, none at all. I’ve just lived my life and that’s it because if I sat down and worried about it, I’d never be able to sleep.” .
“I’m just Kenny Buchanan, I was a world champion, but that’s all behind me, I’m done and I’m done.”
He adds: “I think I’m a Jock Tamson, I don’t put myself above anyone. Everyone is on the same level as me and I don’t feel bad about my life and how it went.”
“I’ve had a good life, I’ve had a great life, I’ve done things that nobody in this country has done and I’ve enjoyed it.”
Buchanan began boxing at age eight, after persuading his father Tommy to take him to the Sparta Club in Edinburgh, and won his first medal at age eight and a half and weighing in at 3rd and 2lbs. He made his international debut aged 17 and turned professional after winning the British amateur title two years later in 1965.
He said: “I was bullied a little bit at school because I was skinny. I had a little chip on my shoulder, but only because the boys wanted to fight me, and then his brother would want to fight me because I would punch him out.
“It was just a left hand that I gave him, and that was it. All I wanted to be was the world champion, the best fighter in the world.”
‘I’ve lived a great life,’ says boxing legend Ken Buchanan
