Burnley midfielder Joey Barton has accepted a Football Association charge that he placed 1,260 bets on matches over the past 10 years.
Barton, who was charged in December, has requested a personal hearing before being sanctioned for breaking FA rules by betting on "matches or competitions" between 26 March 2006 and 13 May 2016.
It is expected Barton will offer mitigation for the breaches.
Players in England's top eight tiers are banned from betting on football.
Barton, 34, rejoined Burnley last month, having left Rangers in November.
In the same month, he was given a one-match ban for breaking Scottish Football Association rules on gambling.
