Western Sydney face the prospect of starting next A-League season in arrears if a Football Federation Australia investigation triggers their suspended points deduction.
Adding salt to their wounds after losing Sunday's A-League grand final 3-1 to Adelaide United, FFA chief executive David Gallop confirmed on Monday the governing body would investigate the lighting of two flares during the match.
One device was let off in the Wanderers' active supporter bays at Adelaide Oval just before kick-off, and another late in the match.
"It's certainly something we need to look at because we've said very clearly over the last few months that flares are not on," Gallop said in Canberra on Monday.
"It is something in the wash-up today and over the next few days we do need to have a look at."
It comes barely three months after the club accepted a suspended three-point penalty and $50,000 fine after FFA found them guilty of bringing the game into disrepute.
The punishment was handed down after a small group of away fans ignited about 20 flares during a match against Melbourne Victory at Etihad Stadium in early February.
FFA said at the time the Wanderers needed to ensure such incidents were not repeated for the next 12 months, otherwise they risked having the suspended sanction triggered.
A loss of points would be a painful blow to the Wanderers, still coming to grips with losing the grand final three times in four years.
