AFLW finals aspirants Geelong will be without Georgie Prespakis for crucial games against the Western Bulldogs and Essendon after the young gun received a two-match ban for a dump tackle.
Collingwood captain Steph Chiocci (striking) and Essendon's Daria Bannister (dangerous tackle) have also been dealt bans.
Prespakis' heavy tackle that concussed St Kilda ruck Erin McKinnon soured Geelong's thumping 50-point victory on Thursday night.
The 19-year-old Prespakis pinned McKinnon's arms before bringing the Saints ruck to the ground in the third quarter.
McKinnon's head slammed into the turf and she was motionless for around a minute before being helped up and taken off the ground.
Match review officer Michael Christian assessed the incident as high contact, high impact and careless conduct, drawing a two-match ban.
Geelong sit sixth and will compete with the Bulldogs (fifth) and Bombers (10th) for finals spots, but will sorely miss Prespakis' drive, especially against her older sister, Essendon star Madison Prespakis.
The Cats can appeal the decision at the tribunal.
Chiocci was banned for a retaliatory strike on Bannister, who had pinned her arms and slung her to the ground in the fourth quarter of the Magpies' win over Essendon on Friday.
The Collingwood skipper hit her head on the ground and quickly lashed out at Bannister, catching her around the throat and chin.
Bannister's dangerous tackle on Chiocci was assessed as careless conduct, high contact and medium impact while Chiocci's striking charge was intentional conduct, high contact and low impact.
Collingwood confirmed on Monday they would accept Chiocci's suspension and she will miss Saturday's away game against St Kilda.
Bannister is due to miss Essendon's trip to face leaders Brisbane.
Fremantle star Kiara Bowers, St Kilda's J'Noemi Anderson, Hawthorn's Sophie Locke, Brisbane's Courtney Hodder and GWS' Haneen Zreika received rough conduct reprimands.
Port Adelaide's Kate Surman and GWS' Jessica Doyle received $400 fines for their second offences of rough conduct and forceful front-on contact respectively.
The Power's Angela Foley received a reprimand for staging.
