Boxing legend Frank Bruno is undergoing scans in hospital amid fears his brain is on a 'slow decline'.
Doctors are trying to determine whether the former WBC heavyweight champion suffered long-term damage from the blows he received during his 14-year career.
The 62-year-old is one of the most revered British fighters of his generation, winning 40 of his 45 professional fights.
He also suffered five knockout defeats and his daughter Rachel said: 'we have learned recently that his brain might be on a slow decline.
'They are just doing scans and tests at the moment. With the impact of his career and constant knocks to the head, it's obviously probably not helped.
'We don't know how fast his brain is going to decline. It's sad but we're a strong family and we want to cherish these moments.'
A source close to Bruno told The Sun: 'Frank's in a great place at the moment and feeling fitter and healthier than he has in years.
'Each week he will be at three or four events talking about his career and working.
'All retired boxers have regular checks, and Frank is no different.'
Bruno has previously said is just 'happy' to be alive after years of mental health struggles after being diagnosed with bipolar disorder.
His life took a downward turn after he was sectioned and admitted to Goodmayes Hospital where he spent a number of weeks.
He has been readmitted to hospital on occasion for treatment since, including recently in 2021 when he hit 'rock bottom' during the coronavirus lockdown.
Bruno is perhaps most famous in the conscience of the wider public for his two fights against Mike Tyson, in 1989 and 1996 - losing both.
His crowning moment was winning the world title, beating Oliver McCall at Wembley in 1995.
