Jesse Bromwich and Tyrell Fuimaono have become the first players to be suspended for "hip drop" tackles since the NRL issued a memo last month calling out the dangerous tackling technique.
The panel of Bob Lindner, Ben Creagh and Sean Garlick found the pair guilty of their charges at the judiciary on Tuesday night. Titans captain Kevin Proctor was also found guilty of biting at the judiciary.
Storm prop Bromwich would have been free to play in Thursday's high-stakes clash with the Eels had he taken the early guilty plea for his grade one dangerous contact charge.
Dragons back-rower Fuimaono was seeking a downgrade to his grade-two charge in a bid to face the Broncos on Friday but will now be sidelined for two matches.
Both men, who were represented by legal eagle Nick Ghabar, were found to have dropped their body weight onto the lower limbs of ball carriers as the third man into tackles.
Bromwich joins a host of his star teammates including Dale Finucane, Cameron Smith, Cameron Munster, Suliasi Vunivalu, Tui Kamikamica and Max King on second-placed Melbourne's unavailable list for the with Parramatta, who are two points behind them in third.
Following an hour of evidence into Bromwich's tackle on Roosters winger Matt Ikuvalu, the jury deliberated for 12 minutes before returning their verdict.
NRL counsel Nick McGrath argued there was "potential for serious injury ... It really is an unacceptable risk of injury".
He submitted that Bromwich made a careless choice to propel his feet from the ground, swivel his hips and land on Ikuvalu's lower limb.
Bromwich told the judiciary "I dropped my body weight to the ground so I [could] grab his knees together" as Ikuvalu was moving forward despite being tackled up top by two Storm players.
The Kiwi enforcer claimed his options were limited and he purposefully avoided spearing in at the legs in a "cannonball" tackle.
Ghabar argued that Bromwich made "careful contact" and was "slow and controlled" as he helped bring Ikuvalu to ground.
McGrath conceded the contact was of low force but said the "mechanics" of the manoeuvre meant it was dangerous and careless nonetheless.
NRL head of football Graham Annesley sent a memo to clubs on July 21 warning against these types of tackles involving heavy impact. Ghabar argued that Bromwich's effort didn't fall into that category as the force was agreed to be soft, but McGrath asserted it was a "textbook example".
In Fuimaono's case, McGrath argued the force in his tackle on Eels prop Junior Paulo was enough to have the grade-two charge stand.
Ghabar claimed that Fuimaono had landed mostly on the ground and said a similar tackle that earned Rabbitohs forward Liam Knight a grade-one charge in the same round was arguably worse.
