Both the Parramatta Eels and Sydney Roosters will finish off the home and away season without key forwards after Ryan Matterson and Victor Radley both entered early guilty pleas.
Matterson won't be available until the first week of the finals after accepting a three-week suspension for a shoulder charge on Manly centre Brad Parker, which at the time resulted in a send-off.
Radley also accepted a three-game ban for a dangerous charge down tackle on Bronco Albert Kelly.
The Roosters star failed to safely charge down a field goal attempt from Kelly, inadvertently taking out the playmaker's legs and leaving him screaming in agony and sprawled out on the turf.
The 23-year-old has already missed five games due to suspension this season, having come under fire for high shots on Kelly and Tevita Pangai Junior in the Roosters-Broncos clash in Round 11.
Raiders forward Corey Harawira-Naera will not make another appearance this season unless his side makes the finals after also accepting a three-game suspension.
Harawira-Naera was sent off in Canberra's 26-16 loss to the Storm, after a shoulder charge which saw Melbourne halfback Jahrome Hughes taken from the field with a concussion.

In other charges, Broncos five-eighth Tyson Gamble will miss the next two games after accepting an early guilty plea.
While Wests Tigers duo Thomas Mikaele and Jacob Liddle, and Cowboys rookie Griffin Neame, will all miss one game each.
Superstar Cowboy Valentine Holmes will head to the judiciary on Tuesday to fight a dangerous contact charge on David Nofoaluma.
