Tyson Fury's much-delayed UK Anti-Doping (UKAD) was scheduled to resume in London on Monday with a verdict expected after the new year - but the controversial Fury failed to show up, and was instead posting videos to social media of singing songs as he was driving.
Neither Fury or UKAD are making any comments regarding the no-show. Reporters waited at the hearing location for as much as six hours before leaving.
The 29-year-old former heavyweight champion and his cousin and fellow heavyweight fighter Hughie, 23, tested positive for the banned steroid nandrolone in February 2015.
The pair, however, were not charged by UKAD until June 2016, by which time Tyson Fury had beaten Wladimir Klitschko. A rematch with the Ukrainian was scheduled for July 2016 but Fury postponed the fight, citing a sprained ankle, on the same day the UKAD charge was announced.
Both Hughie and Tyson Fury have strongly denied the nandrolone charge, claiming the positive was a result of eating wild boar that had not been castrated - a defence similar to the one used by cycling star Alberto Contador when he tested positive for a steroid at the 2010 Tour de France.
The Fury case has been complicated by several other factors, though, as Tyson Fury failed a test for cocaine in September 2016 and later admitted using the recreational drug to deal with depression related to his injury and UKAD problems.
Having already postponed another Klitschko rematch date and facing the prospect of having his titles stripped from him, Fury relinquished his belts on October 12. A day later, the British Boxing Board of Control (BBBoC) suspended his licence and t he Manchester-born fighter's career has been in limbo ever since.
Returns to training and possible fights have come and gone, and hearings with the BBBoC and UKAD have been scheduled and adjourned, with an anti-doping tribunal halted in August after just one day because one of the lawyers involved had a conflict of interest.
There is also the issue of Tyson Fury, who has not fought since that remarkable win over Klitschko more than two years ago, refusing a drugs test in September 2016 - a serious offence, if proven, as it would count as a positive.
