The Warriors prop Russell Packer's apologised on Twitter for urinating on the field prior to the start of last night's match against the Brisbane Broncos at Lang Park.
The National Rugby League has issued the Warriors with an $18,000 breach notice after the incident, which Packer says he's sorry for but is now trying to move on.
The NRL's General Manager of Football Operations, Nathan McGuirk, says that sort of behaviour is completely unacceptable and there is no excuse for it.
The Warriors have five working days to make submissions in relation to the breach notice.
