AFL great Jonathan Brown has received major medical reassurance following life-saving brain surgery, with doctors confirming his tumour was not linked to his playing career or repeated head knocks.
The former Brisbane Lions captain underwent surgery earlier this year after a routine scan revealed a brain tumour described by Brown as being ‘the size of a golf ball’, sparking immediate fears about his long history of concussions in the AFL.
Brown has previously said he was living with what he described as a ‘ticking time bomb’ in his head before the condition was discovered.
But in a significant relief to both Brown and his family, specialists have now confirmed there is no connection between the tumour and the repeated head knocks he sustained during his decorated career.
That clearance was a major emotional turning point for the three-time premiership player, who admitted the uncertainty had weighed heavily on him in the days after his diagnosis.
He revealed the key moment came when his surgeon, Dr Gavin Davis, directly addressed his concerns about concussion.

‘He said categorically this has nothing to do with your previous head knocks in football. It’s completely different, it’s a brain tumour, not related to CTE. That was a relief.’
Brown said that confirmation lifted a huge psychological burden as he processed what had happened.
‘That was a big kick. Like getting kicked in the chest by a big horse.’
The tumour was successfully removed in surgery, with doctors later able to rule out the most serious classifications of cancer.
‘When Gavin came in I had a bit of trepidation and he said, ‘We will start off with some good news. We think we have ruled out the worst’,’ Brown said.
‘You dodge the radiation and more than likely it won’t come back. That was a relief. I didn’t think it would be such a relief but I was holding it in. It was such a deep breath.’
The operation itself was prompted after Brown’s wife, Kylie Brown, insisted he undergo further testing, a decision Brown has repeatedly credited with potentially saving his life.
Scans eventually revealed the tumour during what was intended to be a precautionary health check through an AFL past-players program.

Brown later reflected that without the scan, the tumour may have gone undetected until far more serious symptoms emerged.
‘I am so grateful it was found. I asked how else I would have known and he said, ‘You would have had a stroke or a seizure’,’ he said.
The former forward, who played more than 200 games for the Lions, had long been open about the toll of his playing career, which included multiple concussions and serious collisions.
However, the new medical findings have provided reassurance that his AFL past was not responsible for the brain condition.
The update is particularly significant given ongoing concerns across the sport about the long-term effects of head trauma and conditions such as chronic traumatic encephalopathy (CTE), which has been linked to repeated concussions.
Brown said the clarification brought immediate relief as he worried his football career might have played a role in his diagnosis.
While the tumour diagnosis initially left him shaken, Brown has since spoken about the emotional support he received from his family throughout the ordeal, particularly his children, who reacted strongly when told about his condition.
He is now recovering well following surgery and is expected to make a return to media duties in the coming weeks.
