Tyson Fury has retired from boxing, confirming the news in an expletive-laden message on Twitter.
Fury currently holds the WBA and WBO heavyweight titles.
After beating Wladimir Klitschko on the 29th of November last year, Fury and the Ukranian were set to have a rematch however Fury withdrew twice, first citing an ankle injury and then mental health problems were reported as the reason for the second cancellation.
In a mind-blowingly bizarre tweet, Fury said the following (*this contains strong language): “Boxing is the saddest thing I ever took part in, all a pile of s**t, I'm the greatest, and I'm also retired.”
Fury’s confirmation of his retirement comes under dubious circumstances.
Fury is currently under investigation, having been charged by the UK Anti-Doping Agency (Ukad) in June, after traces of a banned substance were allegedly found in a urine sample.
The fighter has denied allegations of doping.
It has also been alleged he refused to give a sample, having been visited by Ukad.
To make the whole scenario even more odd, when British promoter Eddie Hearn said Fury would never fight again, his trainer and uncle, Peter Fury, responded by explaining that his nephew would return to the ring next year.
Fury has also been given 10 days by the World Boxing Organisation to provide detailed reasons for his second withdrawal from the Klitschko bout.
