Reigning world champion Ronnie O'Sullivan has alleged that Stephen Lee may not be the only top-level snooker player to have taken part in match-fixing.
Briton Lee, a former world number five, was found guilty of match-fixing on Tuesday over matches in 2008 and 2009. He could be handed a lifetime ban at a hearing next week.
O'Sullivan claims Lee's case may only be the tip of the iceberg, and accused the snooker authorities of not doing everything in their power to bring corruption in the sport to light.
He wrote on Twitter that he's heard there's many more players who throw matches and Lee was just caught out.
O'Sullivan says plenty of people have got loads to hide and that's why there's no free speech, but he'll probably get fined for talking about it as the authoritieslike to keep things under the carpet.
World Snooker chairman Barry Hearn reacted by saying that his organisation would ask O'Sullivan to expand on his allegations.
