Davey Browne, born on December 21, 1986 and died September 14, 2015, he was an Australian boxer.
Davey Browne Jr, 28, was knocked out by Carlo Magali of the Philippines towards the end of a 12-round IBF super-featherweight contest on Friday.
Father-of-two Davey life support was turned off after he failed to recover from his injuries.
The Australian Medical Association (AMA) has called for a ban on boxing following Davey death.
Davey death comes just six months after Queensland boxer Braydon Smith collapsed and died following a featherweight bout in his hometown of Toowoomba.
“One punch can kill, whether you are outside a pub on a Friday night or in a boxing ring, and this is the thing that causes young lives to be ended so traumatically,” AMA vice-president Dr Stephen Parnis told Australian broadcaster ABC.
“The way that boxing is designed there will be these times inevitably where someone will get bleeding or irreversible damage to the brain and they will either lose their life or end up with brain damage.”
New South Wales sports minister Stuart Ayres said the Combat Sports Authority, a state government agency, will co-operate fully with police in their investigation of Davey death.
“My thoughts are with David’s family and friends during this tragic time,” Ayres said.
Police confirmed Browne’s death on Monday and said a post-mortem would be conducted.
Davey was knocked out 30 seconds from the end of the final round of the 12-round bout – which would have given him a world ranking.
