Tyson Fury has vacated his Ring Magazine title after announcing his retirement on Friday.

Having said that he would step away from the sport following the defence of his heavyweight world titles against Dillian Whyte in April, the 34-year-old had earlier this week indicated that he would return to the sport, calling out Derek Chisora for a trilogy fight and announcing the appointment of a new trainer, his cousin Isaac Lowe, who has no training experience. 

However Fury, who ended his career with 32 wins, one draw and no losses, has suggested that he is done with fighting as he tweeted on Friday: "Massive thanks to everyone who had an input in my career over the years.

"After long conversations I've finally decided to walk away and on my 34th birthday I say 'Bon Voyage'."

The two-time heavyweight champion of the world then went on to thank many of the key influences in his life, including his father John, wife Paris and former trainers Hughie Fury Sr, Ben Davison and SugarHill Steward.

On Saturday, he confirmed to The Ring that he was vacating the belt, an unpredecented decision by him that indicates his latest retirement statement should be taken more seriously. 

"The Ring Magazine championship has always been the holy grail of boxing. They've been fantastic with me and I've always carried the title with pride," said the Gypsy King, who has yet to make a decision over his WBC belt. 

"The greatest moment of my career was winning the world championship [against Wladimir Klitschko] back in 2015.

"There's the great comeback after that with the three [Deontay] Wilder fights. There have been a lot of great highlights in my career - even the Dillian Whyte fight in front of 94,000 at Wembley. It doesn't get much better than that. And I went out with a bang.

"I've done well out of boxing. The world is open to so many things now. I'm doing a Netflix documentary at the moment. I'm going to be recording an album soon. Who knows, you might even see me on the silver screen." 

The two-time Fighter of the Year became just the third heavyweight, after Floyd Patterson and Muhammad Ali, to win the Ring Magazine title twice, and won every belt possible from the British title upwards. 

The winner of Oleksandr Usyk and Anthony Joshua will now be the successor to Fury's belt, with the fight taking on Saturday in Jeddah, Saudi Arabia in a rematch of last September, when the Ukrainian won by unanimous decision to claim the WBA, IBF, WBO and IBO titles.
