Rugby league heavyweight Phil Gould has deleted a dramatic tweet in which he suggests that the League is on the verge of dropping a bombshell.

The Panthers GM took to Twitter in the early hours of Thursday morning, though the post was deleted shortly after.

"Many in RL circles will be affected by what's about to happen in next 48 hours," Gould wrote.

"The actions about to be taken, will instigate a wide range of reactions.

"We could witness absolute chaos, welcome enlightenment, or even irreparable damage.

"Emotions will run high. I see few winners."

Dramatic stuff from the two-time premiership coach.

The tweet most likely refers to Thursday's impending announcement from the NRL regarding player behaviour.

Amid a disastrous off-season, calls for a blanket rule that would see players facing serious criminal charges stood down have grown louder.

NRL CEO Todd Greenberg and ARL Commission chairman Peter Beattie have both hinted that changes in the game's approach to such issues will be introduced.

St George Illawarra forward Jack de Belin, facing serious sexual assault charges, reportedly knocked back the chance to stand himself down on Wednesday, leaving it in the hands of the game's officials.

An announcement on that matter is expected on Thursday afternoon.

Similarly, the findings into the investigation into Cronulla's salary cap situation are also due following the ARLC board meeting on Thursday.

The Sharks are expected to be hit with a fine for several alleged breaches.
