Scottish boxer James Murray died Sunday in Glasgow of injuries suffered in a title fight with Drew Docherty, leading to a renewal of calls for the sport to be banned in Britain.
Richard Morgan, a spokesman at Glasgow's Southern General Hospital, said doctors had pronounced Murray "clinically dead" Saturday but left him on a life support machine.
They reassessed his condition Sunday, decided he was dead and then removed him from the machine.
Murray, 25, underwent brain surgery following the knockout by Docherty in the final round of the British bantamweight championship fight Friday night.
Docherty, who appeared anxious about Murray's condition even as he was being hailed the winner in the ring, was said to be "shattered" by the news of his death.
His manager, Tommy Gilmour, issued a brief statement that read: "Words just cannot express how badly we feel about James' death. Our thoughts are with his family and friends."
Murray's record was 14-2-0.
