Queensland is facing a further penalty over the Maroons having 14 men on the field in the opening State of Origin game at Adelaide Oval.
The NRL on Friday issued the Queensland Rugby League (QRL) with a breach notice following events in the first half of the match on May 31 that the Maroons won 26-18.
The QRL faces a proposed fine of $30,000 for the alleged breach of NRL rules.
In a statement, the NRL said the Maroons had an extra player on the field for approximately 30 seconds in the 18th minute of play.
The alleged breach occurred following an injury to Maroons player Tom Gilbert, who sustained a shoulder dislocation and had to come from the field with his arm hanging by his side.
"Maroons player Lindsay Collins entered the field of play to replace Gilbert, however, Gilbert failed to leave the field of play, resulting in both players being on the field at the same time," the NRL said.
Referee Ashley Klein awarded a penalty to NSW after spotting that Queensland had one too many on the ground.
The QRL has 5 business days to respond to the notice.
