The Bulldogs have stood down playmaker Lachlan Lewis pending the outcome of an investigation into an alleged incident.
On Friday night the club said it was aware of an alleged incident and was working with the NRL Integrity Unit regarding the matter.
The club said Lewis would be stood down until the investigation was complete and would not comment further at this stage.
Lewis had originally been named at five-eighth to make his seventh NRL appearance of the year but will now miss his side's round 24 clash against the Sea Eagles.
Lewis is in his fourth season at the Bulldogs, having made 43 appearances with 15 wins and 28 losses, scoring six tries and kicking one field goal.
The Bulldogs also announced on Friday night that they had issued Adam Elliott with a club breach notice for bringing the game and the club into disrepute after an incident at a Gold Coast restaurant.
Elliott had already been issued a breach notice by the NRL after he was alleged to have brought the game into disrepute and failed to comply with biosecurity protocols. It was also proposed by the NRL that he must complete education and training on top of his fine.
