The NRL is set to trial a new concussion regulation, allowing for players to be sent to the sin bin for up to 15 minutes following a high tackle that results in an opponent being sidelined for the match.
As the pre-season trials kick off this Friday, The Sydney Morning Herald has reported that a group of coaches approached the NRL with suggestions to modify the concussion rules. However, league officials have confirmed that no alterations will be made for the upcoming season.
Last season, fans experienced frustration and confusion due to inconsistent enforcement of penalties against players committing high tackles.

Modifications to the sin bin rule could be on the horizon. Nine
According to the new proposal, the sin bin will only come into effect if the injured player fails a head injury assessment.
The offending player will remain on the field until the results of the HIA are announced, as reported by The Herald.
If the injured player is deemed unfit to return, the match will pause, and the offender will be sin-binned for a duration of 10 minutes.
The NRL did not provide a comment regarding these proposals when approached by The Herald.
During the off-season, the NRL indicated that referees would be taking a firmer stance on sloppy play-the-balls in the initial rounds.
Additionally, the obstruction rule will be a point of focus, with referees instructed to reward effective attacking plays rather than penalising defenders who appear to be obstructed.
