Snooker's governing body is set to investigate allegations that Quinten Hann agreed to throw a match for money.
The World Professional Billiards and Snooker Association (WPBSA), which is also known as World Snooker, said it had procedures in place to address the claims.
The Sun alleged that Hann had agreed to accept £50,000 to lose a match at the China Open.
It said he had made the deal with one of its undercover reporters, who was posing as a frontman for an illegal betting syndicate.
The newspaper also alleged that Hann had offered to fix the result of a match at last month's World Championships in Sheffield's Crucible arena.
A spokesman for the WPBSA said: "The WPBSA is aware of an allegation of match fixing made by the Sun newspaper against one of its members.
"The WPBSA treat any such allegations seriously. Like any other sport, the WPBSA has procedures in place to address these allegations.
"Until these procedures have been completed, the WPBSA will not be commenting further."
