Paul Gallen is set to be called to front the Cronulla board next week to explain a social media attack in which he used an expletive to hit out at the NRL.

Powerbrokers at League Central were on Thursday night believed to be angry at the comment made by the suspended Sharks and NSW captain, particularly given his leadership position within the game.

He faces punishment including a possible hefty fine over the spray on Twitter, made in the wake of Cronulla chief executive Steve Noyce's sacking, but the NRL is expected to wait and see how the matter is dealt with by the Sharks before determining if any further action is needed. Gallen left little doubt about his thoughts on chief executive Dave Smith's management when he posted on his official Twitter account early on Thursday morning, responding to a news alert on the exit of Noyce: "Steve Noice (sic) actually cared about players from cronulla's feelings. Couldn't say that about any other c--- from Nrl." After several other posters urged him to delete the post, it soon disappeared.

The Sharks parted ways with respected administrator Noyce on Wednesday as part of what they described as a restructure of the club's hierarchy. This has left the wooden spooners again without a chief executive of their football department as they seek to rebound from two seasons marred by an ASADA investigation into their 2011 supplements program.
