Liang Wenbo has been suspended from all World Snooker Tour events with immediate effect following his conviction for domestic-related assault.
The WPBSA have imposed the sanction on the Chinese player, who was fined and handed a 12-month community order after pleading guilty to assaulting a woman in Sheffield.
The matter will be referred to the WPSBA Disciplinary Committee, where a formal hearing will take place.
Former English Open winner Liang, who will subsequently miss the World Championship and remain absent from all events until the conclusion of the hearing, has the right to appeal the decision.
Jason Ferguson, Chairman of the WPBSA, said: “The decision to suspend a player with immediate effect is not one taken lightly.
“However, due to the violent and criminal nature of this offence, I have reached the decision that this is the only appropriate action to be taken pending the outcome of the formal disciplinary process.”
