“In accordance with the collective bargaining agreement with the RLPA [Rugby League Players Association], information concerning the NRL’s proposed sanction will not be disclosed until the player has had the opportunity to respond to the alleged breach and the matter is finalised,” the NRL said.

Mam was heavily criticised over the incident, with state Attorney-General Deb Frecklington saying “for many Queenslanders, this outcome doesn’t pass the pub test” while Deputy Premier Jarrod Bleijie described the $850 fine and six-month licence suspension as “disgraceful” and a “slap on the wrist”.

However, new Broncos coach Michael Maguire said Mam had “learnt a lot from this moment”.

“It’s really up to him, but each day is a new day to make sure that he makes amends and keeps moving forward,” he said.

While he was yet to respond to the breach notice, Mam said after his court appearance last week that he was sorry for his actions and the resulting accident.

“Today is an important step in owning my actions and starting to make things right. To all the people involved in this accident, I’m truly sorry,” Mam said.

“This incident isn’t a reflection of who I want to be, or what’s expected of me as a role model. To the NRL, the Brisbane Broncos, the fans and my family, I’m sorry.

“I promise to work on being a better person and representative of the club and the game that I love.”
