Proceedings were due to begin in Manchester on Wednesday (February 6) but Freeman's barrister Mary O'Rourke applied for a 48-hour extension.

The extension was granted by a three-person panel.

Freeman did not attend the city's St James' Buildings himself and no reason for the delay was revealed.

According to cyclingnews, a further preliminary application was tabled yesterday.

With the submission having expected to take a day to assess, it meant the case was again delayed.

It is now expected to start on either Monday or Tuesday (February 11 or 12).

Freeman has been accused by the General Medical Council (GMC) of "inappropriately" providing medical treatment to non-athletes, and failing to inform three patients' GPs of "medication prescribed and reasons for prescribing".

He is also accused of poor record keeping and failing to maintain an "adequate record management system".

The doctor denies any wrongdoing.

Freeman faces accusations that he ordered testosterone to enhance the performance of an athlete.

A total of 30sachets of testogel, a substance banned by the World Anti-Doping Agency (WADA), were posted to British Cycling's headquarters in 2011.

According to Freeman this order was placed in error, but an investigation carried out by the GMC has alleged that this explanation was dishonest.

He has been accused of contacting company Fit4Sport Ltd to ask for confirmation that the order was a mistake.

Freeman also allegedly told UK Anti-Doping (UKAD) investigators that the testogel had been ordered for a "non-athlete member of staff".

The GMC has also concluded that this was a lie.

Freeman was due to be quizzed on who he ordered the testogel for and whether he ordered it for staff members without their knowledge.

Staff from both British Cycling and Team Sky are expected to be called as witnesses at the tribunal, to confirm if they were aware medication had been ordered for them.

Freeman left British Cycling in 2017, with the doctor citing stress over ongoing investigations as the reason for his resignation.

Poor health was given as the reason he did not provide evidence to a Parliamentary Select Committee hearing in March the same year.

Any new evidence that emerges from the tribunal could spark a fresh UKAD investigation, which could lead to Freeman being charged with an anti-doping rule violation if the evidence warrants it.

Freeman has also been at the centre of controversy regarding the jiffy bag saga surrounding five-time Olympic gold medallist and Tour de France champion Sir Bradley Wiggins.

He was accused of failing to keep adequate medical records, after he claimed a mysterious package sent to Sir Bradley at the Critérium du Dauphiné in 2011 claimed the legal decongestant flumicil.

Neither Freeman nor Team Sky could prove it after his laptop containing medical records was allegedly stolen.

UKAD announced in November 2017 that no doping charges would be pursued after concluding their investigation into the jiffy bag, after stating they were unable to confirm or refute the account that the package contained fluimucil, despite a "very significant effort".

In December, broadcast giant Sky announced it will end its involvement in cycling at the end of the 2019 season, claiming it was "the right time" to leave.

To date the team has registered 322 total victories, including eight Grand Tours, 52 other stage races and 25 one-day races.
