Jamie Jones has been suspended from snooker with immediate effect over allegations he was involved in match-fixing.
Jones is accused of being part of a plan to fix the outcome of a match between fellow Welshman David John and Graeme Dott at the International Championship qualifiers in 2016.
John, who dropped off the tour at the end of last season, was suspended in May pending the outcome of the hearing.
Now, the WPBSA say Jones also has a case to answer for his alleged involvement and will face a formal hearing.
The WPBSA have stressed in their statement that no matches played by Jones are under suspicion in this matter and there is no suggestion of wrongdoing against Dott.
Dott thrashed John 6-1 at the 2016 International Championship qualifiers in Preston, with John winning the first frame with a 79 break before mustering just 45 points in the next six frames.
Jones was due to face Zhao Xintong in Barnsley in the qualifying round of the International Championship on Friday, with Zhao subsequently receiving a bye.
Jones’ breakthrough came at the 2012 World Championship – where he reached the Quarter-Finals on debut at The Crucible.
He returned to Sheffield this year, recovering from 8-5 down to again defeat Shaun Murphy 10-9 in the First Round before losing out to Kyren Wilson.
