Joey Barton is facing a lengthy ban after pleading guilty over FA betting charges
Burnley midfielder Barton, 34, has requested a personal hearing before the FA commission over charges that he made 1,260 bets during a 10-year period against FA rules.
The outcome is likely to decide the fate of the former Manchester City and QPR player, who has a contract at Turf Moor until the end of the season.
A lengthy suspension, given the severity of the charges, is a probability, and earlier this season the FA banned Frome Town's manager Nick Bunyard for three years over 45 bets.
Barton was charged by the FA in December following a months-long investigation of allegations that set the alarm bells ringing in September.
He was allowed on request to delay his response to the FA, initially set at January 5, until last Tuesday.
Barton's career at Burnley could be over in a matter of weeks due to making 1,260 bets
Barton rejoined Burnley last month after an unsuccessful spell at Rangers ended following a training-ground row with manager Mark Warburton.
His short-term contract at Turf Moor is believed to contain safeguards should he incur an FA ban.
Burnley have not commented on the charges, insisting it is a matter for Barton and the FA.
Manager Sean Dyche said: "If we needed to do anything we would, but we are not really involved here."
But Dyche has admitted he is delighted with how well Barton has stepped back into the side, however short-lived his return may be.

Dyche said: "If he'd gone to another club and had to see how they work, that might be different.
"But he knows the requirements here. That doesn't mean he's going to play well but it can give you a helping hand.
"There are no guarantees but I thought he would at least give a good account of himself, and I thought he played very well.
"He did more than give a good account of himself. That's why I thought he could come back in because he gets it here."
