Athletes do not have to show up to these hearings in person, but Fury was widely expected to show his face in an attempt to clear his name.
Both Fury and his cousin and fellow heavyweight Hughie, 23, tested positive for a banned substance in February 2015, but were not charged until June 2016.
That came after Fury had beaten Wladimir Klitschko for the IBF, WBA and WBO world titles but he then vacated the belts citing problems with depression and cocaine use.
The 29-year-old is currently without a boxing licence due to the British Boxing Board of control’s suspension.
He has repeatedly postponed his drugs charge hearing but only recently the heavyweight boxer has stated his intention to get back into the sport, calling out the likes of Tony Bellew and Anthony Joshua.
But Fury’s no-show at his UKAD hearing yesterday has raised further questions about his commitment to clearing his name.
Members of the tribunal were allowed to leave after 3pm but the Guardian claim the agency would not confirm whether the hearing officially started or not.
Both Tyson and Hughie Fury have strongly denied the charges, claiming the positive test was due to the pair eating wild boar that hadn’t been castrated.
It’s a similar reason given by cyclist Alberto Contrador when he tested positive for steroids at the 2010 Tour de France.
It remains to be seen whether Fury will be present at the hearing that is expected to last this whole week.
