Former heavyweight boxer Joe Bugner has died at the age of 75.
Bugner twice held the British and Commonwealth heavyweight titles and was a three-time European heavyweight champion.
He faced Muhammad Ali and Joe Frazier in back-to-back bouts in 1973, before facing Ali again - for the world title - in 1975.
"It is with great sadness that the former British, European and Commonwealth heavyweight champion, and world championship contender Joe Bugner has passed away at his care home in Brisbane, Australia," said the British Boxing Board of Control.
"The British Boxing Board of Control passes on its condolences to Joe's family."
Bugner was consistently ranked among the world's top 10 heavyweights throughout the 1970s and was known for technical ability, toughness, durability and willingness to take on the best.
During his 83-fight career, he also shared the ring with other notable heavyweights such as Earnie Shavers, Henry Cooper and Frank Bruno.
Bruno called it a "sad day for boxing", while Queensberry promoter Frank Warren also paid tribute to Bugner.
"He participated in the first fight I did on ITV - a great man who will be missed. I'm sending my regards to his family. May he rest in peace," said Warren.
