Video report by ITV News Anglia's Malcolm Robertson.
A young boxer from Norfolk is on life support in hospital, after being knocked out unconscious during his first ever fight.
Kuba Moczyk was fighting at the Atlantis Arena in Great Yarmouth on Saturday after months of training.
In the final round, Kuba was knocked to the ground from a single punch.
The 22-year-old is now critical in intensive care at James Paget Hospital in Gorleston.
His twin sister Magdalena said he suffered a bleed to the brain and is now praying for his recovery.
Kuba was looking forward to the big day, he really wanted to be in that ring. He was training long and hard for it.
Kuba's family are now hoping to transfer him to a specialist hospital abroad where they can help wake him up.
A fundraising page set up to support Kuba's family has raised more than £3,500.
