Former world middleweight champion Alan Minter has died aged 69.
He won Olympic bronze at Munich in 1972 and went on to capture the British and European middleweight titles before he was granted his opportunity to fight on the world stage.
The British fighter, who was born in Crawley, claimed the WBC and WBA titles with a split decision win over Vito Antuofermo in March 1980 in Las Vegas but Minter's reign lasted a matter of months as he was beaten by Marvin Hagler at Wembley Arena.
The southpaw ended his professional career the following year after being stopped inside three rounds by compatriot Tony Sibson, retiring with a record of 39 wins, nine defeats and one no-contest.
"The stewards and staff of the British Boxing Board of Control are very saddened to hear of the passing of former world middleweight champion Alan Minter," a brief BBBoC statement said.
"Our sincerest condolences are sent to his family at this time."
Former world heavyweight champion Frank Bruno led the tributes to Minter, writing on Twitter: "Alan Minter RIP.
"Alan and I worked together many times a great boxer in his day I would ask people to look at the old footage of him fighting a great boxer a sad day for British Boxing RIP 'Boom Boom'."
Former two-weight world champion Ricky Hatton added: "Just heard the very sad news that our boxing family has lost one of our own in former world champion Alan Minter.
"You'll always be a British boxing legend and a gentleman Alan. My love and very best wishes go out to Ross and the whole Minter family at this time."
