The NRL's Match Review Committee has announced four charges from the matches on Sunday, highlighted by two forwards from the Sydney Roosters.
While all players have escaped suspensions, Victor Radley faces a potential one if he contests his charge at the judiciary.
Radley received a Grade 1 careless high tackle charge for a late hit on Patrick Herbert during the unexpected loss.
With Radley now having three or more infractions on his record, he will incur a $3000 fine with an early guilty plea, but if he challenges it, he risks a two-match ban during the regular season's final stretch.
The Roosters' defeat leaves them eager to improve as they approach the finals while vying for the minor premiership, particularly with Radley and Siua Wong now expected to be available, offering a boost to Trent Robinson.
Wong also faced a Grade 1 careless high tackle charge for his tackle on Jock Madden in the first half, with the option to pay $1000 for an early guilty plea or $1500 if he contests and loses.
Madden was additionally charged after the Tigers' surprising victory, receiving a Grade 1 careless high tackle charge for a hit on Reece Robson, which allows him the same options for fines as Wong due to it being his first offence.
In earlier action, the Cronulla Sharks managed to secure a crucial win against the Gold Coast Titans, where Briton Nikora was the sole player charged for dangerous contact with Jayden Campbell.
Since this is his first offence, he faces a fine of $1000 with an early guilty plea or $1500 if he opts to challenge it and loses.
