World heavyweight champion Tyson Fury says he has retired from boxing according to his twitter handle.
The Briton, 28, withdrew from a rematch with Ukrainian Wladimir Klitschko, scheduled for 29 October, because of reported mental health issues.
Fury, who holds the WBA and WBO titles, faces a hearing in November into a charge for an alleged doping violation.
“Boxing is the saddest thing I ever took part in,” read his tweet, adding: “I’m the greatest, and also retired.”
Boxing is the saddest thing I ever took part in, all a pile of shit, I'm the greatest, & I'm also retired, so go suck a dick, happy days.😀😀😀

Fury had been scheduled to earn the biggest purse of his career for his second fight with Klitschko at the Manchester Arena this month.
He postponed the original rematch against the Ukrainian, which was scheduled for July, after injuring an ankle in training.
He has been given 10 days by the World Boxing Organisation to provide detailed reasons for his second withdrawal.
