Former world snooker champion Stuart Bingham has admitted breaching the sport's betting regulations, claiming he was "not clear on the rules".
Bingham, who defeated Shaun Murphy in the 2015 final, found out in December that allegations were being investigated by the World Professional Billiards and Snooker Association (WPBSA) and has since confessed to betting on the outcome of matches involving other players.
There is no suggestion the 40-year-old has been involved in match fixing.
"This was just a case of me not being clear on the rules," said the world number three, who could face a ban.
"I did not know I was not allowed to bet on other players' matches, I thought it was just my own I could not bet on, and I have never done that.
"I have nothing to hide on the matter and have cooperated fully with the investigation and I now await the outcome."
A WPBSA statement read: "Following an investigation into an alleged breach of the WPBSA Betting Rules by Stuart Bingham, a decision has been taken today that there is a case to answer.
"The matter has now been referred to the WPBSA Disciplinary Committee where a formal hearing will take place at a venue and date to be confirmed.
"This relates to bets placed on snooker in contravention of the WPBSA Betting Rules.
"There is no suggestion of any match manipulation or corruption in this case."
