“Preventable deaths and disability in young people will continue as long as MMA and boxing exist,” the brain injury charity Headway has warned after tragic passing of boxer John Cooney.
Cooney died aged 28 on Saturday after suffering an intracranial haemorrhage at a title fight in Belfast a week earlier. He had surgery to relieve pressure on his brain but sadly died a week later at the city’s the Royal Victoria Hospital.
Speaking on behalf of his family, Cooney’s promoter MHD Promotions said: “It is with complete devastation that we have to announce that after a week of battling for his life John Cooney has sadly passed away.
“Mr and Mrs Cooney and his fiancee Emmaleen would like to thank the staff at Belfast’s Royal Victoria Hospital who have worked tirelessly to save John’s life and for everyone who has sent messages of support and prayers.
“He was a much-loved son, brother and partner and it will take us all a lifetime to forget how special he was. RIP John ‘The Kid’ Cooney.”
Brain injury charity Headway said its “heartfelt condolences go to his family and loved ones during this incredibly difficult time”.
It continued: “Our thoughts are also with John’s opponent for his final bout, Nathan Howells, for whom John’s death will no doubt be incredibly hard to bear.
“Every boxing related death and brain injury is tragic but sadly no one should be surprised when they occur. For as long as boxing or MMA exists, we will continue to see preventable deaths and disability in young people.”
The news prompted a similar reponse from brain injury charities globally. The Canadian charity, the BC Brain Injury Association, for example, said: “The tragic death of Irish boxer John Cooney serves as a stark reminder of the devastating impact of brain injuries.
“Cooney, a rising star in the boxing world, passed away following complications from a brain injury sustained during a match. His story is devastating, but not unique—athletes in contact sports continue to face life-altering consequences due to concussions and repearted head trauma.
“This loss underscores the urgent need for increased awareness about the risks of traumatic brain injury (TBI). Whether in professional arenas or youth sports, we must prioritize prevention, research, and support for those affected.
“Let’s use this moment to advocate for change—because no sport should come at the cost of a life.”
