Former world heavyweight champion Leon Spinks has died aged 67.
The American achieved a famous upset win over Muhammad Ali in 1978, in just his eighth professional fight.
The former US marine died on Friday evening in Henderson, Nevada, with his wife Brenda Glur Spinks by his side.
“Leon fought his battle with numerous illnesses resiliently, never losing his trademark smile. Showing true Spinks determination, he never threw in the towel,” the statement added.
Born in St Louis, Spinks won gold at the 1976 Olympics in Montreal, then rose to greater prominence a little more than 18 months later, given the nod via a split decision to stun Ali and claim the WBC, WBA and lineal heavyweight titles.
In one of the biggest upsets in the history of the sport, Spinks defied his 10-1 underdog odds with bookmakers to prevail after 15 rounds, winning 145-140 and 144-141 on two scorecards while a third went 143-142 in favour of Ali.
His reign as world champion lasted exactly seven months as a sharper and fitter Ali gained revenge in a rematch in September 1978, becoming the first three-time lineal heavyweight champion after a comfortable points win.
Spinks did get another opportunity for heavyweight glory in June 1981, but was stopped inside three rounds by Larry Holmes.
Spinks then dropped down to cruiserweight but was defeated by WBA champion Dwight Muhammad Qawi in 1986. He boxed on for another nine years and finished with a record of 26 wins, 17 defeats and three draws.
Known for his gap-toothed grin, Spinks’ battles in the ring contributed to his ill health in later life. It was found he had shrinkage in the brain in 2012 before his cancer diagnosis was confirmed a few years later.
His son Cory, 42, is a former undisputed welterweight champion who also won a world title in the light-middleweight division.
Spinks’ younger brother Michael, 64, was undisputed light-heavyweight champion for a period in the 1980s, before moving up to heavyweight, where he won the IBF title and avenged Leon’s loss to Holmes.
