The UK Anti-Doping (Ukad) hearing examining allegations Tyson Fury took a performance-enhancing substance has been postponed.
Press Association Sport reports Ukad took its decision due to a potential conflict of interest on its panel.
The hearing began on Monday and was expected to conclude this week. A future date for when it will resume is yet to be confirmed.
Fury has denied wrongdoing, and previously threatened to sue Ukad.
The 28-year-old is back in training but has not fought since beating Wladimir Klitschko to become heavyweight champion of the world in November 2015.
He had his licence revoked in October as he dealt with mental health problems, but had been aiming to return on the Billy Joe Saunders-Avtandil Khurtsidze undercard on 8 July.
Ukad charged both Fury and his fellow heavyweight boxing cousin Hughie, 22, with the “presence of a prohibited substance” on 24 June 2016.
Prior to that, the Sunday Mirror reported that traces of banned substance nandrolone had been found in a urine sample taken from Fury in February 2015.
Frank Warren, who promotes both Tyson and Hughie Fury, described the postponement as “ridiculous”.
He added: “We want to see the end of this. It’s gone on and on. It’s been over their heads for two years. It’s taken all this time to get there and in the meantime there’s no outcome.”
