A hearing has been scheduled for tonight, with a three-man panel chaired by retired judge Trevor Maxwell to determine the Pirates' fate.
ARL chairman Cameron McGregor confirmed expulsion from the finals was one option.
Pirates coach Grant Pocklington admitted fielding a weakened side but strongly denied attempting to manipulate the playoff schedule.
"What happened to Papakura was the result of our decision, it wasn't the reason for our decision," Pocklington said.
"Obviously Papakura are going to be pissed off, but if we were in cahoots and trying to designate a score, we wouldn't let 100 be put on us."
The club had seven injured players, three away for personal reasons and had rested the remainder ahead of the finals, Pocklington said.
Having beaten Otahuhu the week before to secure third place, there was nothing riding on the match for Pt Chev. The club could not use players from their reserve team as that team still had a chance of making thefinals.
Having been transformed from a lower division club on the brink of extinction to a genuine Fox contender under the guidance of former Warriors legends Stacey Jones and Awen Guttenbeil, Pt Chev have been the feelgood story of Auckland club league in recent times.
Guttenbeil is no longer associated with the club, while Jones relinquished the coaching reins this season to take up a position with the ARL.
Jones was granted dispensation to remain as the club's technical adviser, however he was away attending a funeral at the weekend and had nothing to do with selecting the Pt Chev team that took the field on Saturday.
"I guess it's not a good look," Jones said. "But I can see the reasoning behind the coach wanting to rest his players. We couldn't go any higher or lower."
Papakura chairman Bill McEntee said a rumour Pt Chev would field their third team began circulating last Thursday.
"I thought, 'Jeez, they won't stoop that bloody low because that is a low blow.'
"And they did. If they were beaten fair and square then you've got no problem," McEntee said.
"But all year we've played the Fox and then they do this to manipulate the competition to their own needs.
"We'd beaten them soundly twice. They couldn't handle us, they wanted to play Marist and so they manipulated it.
"It's really against the spirit of the game as far as I am concerned. It's left a really bad taste in our mouths. When I heard about it I was disgusted."
