North Melbourne defender Jackson Archer, Richmond spearhead Tom Lynch and Hawthorn backman Jack Scrimshaw have all had their respective suspensions upheld at the AFL Tribunal.
Archer will miss games against Melbourne, Adelaide and Sydney through his three-match rough conduct ban over the sickening collision that knocked out Western Bulldogs defender Luke Cleary.
North can still take the case to the AFL appeals board but at this stage are unlikely to do so.
After 39 minutes of deliberation on Tuesday evening, the tribunal of chairman Jeff Gleeson, Shane Wakelin and Jordan Bannister, upheld Archer's ban.
Dogs defender Cleary was knocked out when Archer's knee made contact with his head in a contest in Saturday night's match at Marvel Stadium.
Play was stopped and Cleary received medical attention before being taken to hospital. He will miss the Bulldogs' match against Collingwood on Friday night under concussion protocols.
The match review officer graded Archer's actions as careless conduct, severe impact and high contact, drawing a three-game suspension.
North's defence centred around Cleary's decision to go to ground to collect the ball.
"I expected him to pick up the ball and stay on his feet," Archer said, noting players were trained not to go to ground.
Archer said once he saw Cleary's knee hit the ground, he slowed down and braced for impact, but AFL lawyer Andrew Woods said he hadn't taken "reasonable care" to avoid the collision.
Gleeson acknowledged rules encouraged players to keep their feet but this didn't always happen and "players need to be aware", saying Archer had "slowed too little and too late".
Richmond spearhead Lynch will miss Saturday's clash with Port Adelaide for rough conduct on Carlton's Tom De Koning.
Richmond argued Lynch's contact with De Koning in Thursday night's clash, where his shoulder hit the Blue's jaw, was due to Carlton defender Jacob Weitering pushing him.
"I'm in a vulnerable position and I react to get my head out of the dangerous position it was in," Lynch said.
Lynch said he had not attempted to bump or make high contact.
Woods argued the Weitering push was "not of any significant force" and Lynch had opted to bump.
After just 17 minutes of deliberating, the tribunal of Gleeson, Scott Stevens and Paul Williams found Lynch had intended to bump De Koning and did so, and it was not caused by the push from Weitering.
The rough conduct charge and "careless" grading were upheld.
Hawk Scrimshaw is suspended for three matches for his high hit on Essendon's Jordan Ridley on Friday.
Scrimshaw, who did not speak, pleaded guilty to striking Ridley, to careless contact and high contact but Hawthorn unsuccessfully submitted it should be high impact, not severe, in a bid to reduce the ban to two games.
Ridley was assessed post-contact and was later diagnosed with concussion and will miss at least one game.
Scrimshaw is already out of Thursday's game against Carlton after he was concussed in a head clash with teammate Josh Battle.
He will also be suspended for games against GWS and Port Adelaide.
Melbourne are yet to decide whether they will challenge Aidan Johnson's one-match suspension for rough conduct on Giants forward Callum Brown.
Sydney accepted Justin McInerney's three-match ban for the bump that concussed Brisbane's Brandon Starcevich.
