Tyson Fury’s battles with mental health are well-documented but his father believes they began when his son was just 10-years-old.
Fury’s second spell in boxing continues on February 22 when he faces WBC heavyweight world champion Deontay Wilder in a rematch of their December 2018 epic draw.
The 31-year-old had a near three-year hiatus out of the ring when those issues reared again following his brilliant victory over Wladimir Klitchsko to win the WBA, IBF, WBO, IBO in November 2015.
Fury has overcome addictions to alcohol and cocaine and lost the weight gained since then to turn around his fortunes.
And speaking about his son, John Fury has revealed that battles with mental health run in the family.
‘I noticed when he was 10, 11, 12 he would be happy one minute then he would be sad,’ he told ITV’s Good Morning Britain. ‘He had big mood swings.
‘I’ve lived with it all my life, but I always find something to occupy my mind. My dad had big problems with his mental health, he was medicated all his life.’
Going into next weekend’s bout with Wilder at the MGM Grand Garden Arena in Las Vegas, Fury is yet to taste defeat – having won 29 of his previous 30 fights and drawing the other against the American.
But despite the ‘Gypsy King’ being one of the best heavyweights at present, his father has revealed that it took him a while to get interested in the sport as a child.
‘In the early years he was a poorly child who didn’t show much interest in boxing,’ he said.
‘I used to get my gloves on and mess around with the children but he was overweight, plump, shy, he was an inward kind of baby.
‘But when he got to eight, nine or 10 I realised he wanted to do it passionately.’
