Errant trio Eddie Betts, Ryan Houlihan and Andrew Walker have been suspended from the Blues for a month and will not be eligible for NAB Cup selection.
The trio incurred their suspensions following a drunken episode aboard a cruise ship just prior to the Christmas break.
"They will be suspended from the club immediately for a period of one month, and during this time they will complete all training away from the rest of the player group, and with the Northern Bullants," club president Stephen Kernahan said.
"They will also be unavailable for selection for the NAB Cup, and we know this will impact on their preparation for the home and away season - clearly it was completely unacceptable."
