Britain’s world heavyweight champion Tyson Fury announced his retirement from boxing on Monday at the age of 28, days after the defense of his titles was postponed once again.
“Boxing is the saddest thing I ever took part in, I’m the greatest,” Fury said in an expletive-filled rant on Twitter.
Fury, WBA and WBO and champion, had been due to defend his titles against Wladimir Klitschko in July but pulled out with an ankle injury.
The fight was rescheduled for this month but postponed again due to an unspecified medical condition.
Fury has tested positive for cocaine, ESPN reported last week citing a leaked letter sent by the Voluntary Anti-Doping Agency (VADA). Reuters was unable to verify details of the report.
Fury’s uncle and trainer Peter Fury said recently that the boxer was “almost at breaking point” and receiving professional help.
