More than 50 players will enter the last round walking a judiciary tightrope, with prior offences threatening to rule them out of more than half of the finals series.
Under NRL rules, players receive an extra-match ban for previous offences on their record.
If a player has two or more priors, an extra two games are added to the base penalties for charges.
It means that a grade-two careless high tackle that would normally carry with it a one-game ban, can blow out to two or three finals matches depending on a player's record.
Those with two or more offences on their record also can't accept fines for any shoulder charge, dangerous throws or crusher tackle charges.
The NRL does give players one extra warning in finals matches, but that does not come into effect until next week.
Of the 10 teams still in finals contention headed into round 27, a total of 52 players have been named to take to the field this weekend with at least one mark on their record.
And no club is more at risk than the Bulldogs, who have had a wretched year with the match review committee.
Canterbury will have 10 of their stars enter Saturday night's clash against Cronulla with a prior offence on their record.
That list includes the likes of Stephen Crichton, Matt Burton and Viliame Kikau, who would face a minimum ban of two finals matches for any charge that carries a suspension.
Sam Hughes, Jacob Preston and Sitili Tupouniua also fall into the category of having two or more priors.
The Bulldogs had a total of 31 charges from the match review committee this year, nine more than the next worst offending team in Canberra.
Cameron Ciraldo's team are not alone however in potentially nervous waits for charge sheets this weekend.
The Dolphins, Sydney Roosters, Warriors and Brisbane all have six players carrying priors into the final round, meaning they too are at risk of being heavily impacted.
And when it comes to big names, Nelson Asofa-Solomona, Ronaldo Mulitalo, Scott Sorensen and Felise Kaufusi headline the list with two or more priors.
The vast majority of those are for minor offences, with the NRL handing out more than $275,000 in judiciary fines across the board this year.
