Worried sponsors have contacted snooker's governing's body following Ronnie O'Sullivan's comments that corruption in the sport is rife.
World Professional Billiards and Snooker Association chairman Jason Ferguson called the five-time world champion's claims "absolute rubbish".
He also told him to act "in a manner befitting a professional sportsman".
O'Sullivan has retracted the claims he made after Stephen Lee was found guilty of seven counts of match-fixing.
WPBSA chairman Ferguson said: "We have had contact from sponsors concerned about Ronnie O'Sullivan's comments, that have now been retracted and were without substance.
"I travel the world promoting a sport that involves gentlemanly behaviour and fair play, and I have had comments expressing serious concern."
Following the verdict on Lee last week, O'Sullivan tweeted: "I've heard there's many more players who throw snooker matches."
A few days later he claimed his comments were taken out of context and that he had no intention of damaging the integrity of the sport.
Ferguson added: "We have worked very hard to get snooker clean. When someone comes out with absolute rubbish it undermines the good work and it isn't just anyone, it is our world champion."
