Steph Chiocci's crude bump on Libby Burch will sidelined the Collingwood captain for the last two games of the AFLW season.
Match review boss Michael Christian charged Chiocci with forceful front-on contact and handed her a two-game suspension.
If the Magpies go to the tribunal, they risk a three-game ban for one of their key players.
Chiocci cannoned into the Western Bulldogs player during the first quarter of Sunday's match in Moe.
Birch suffered a cut head and had to leave the field but returned in the second term.
She was also charged with striking Mo Hope but is among six players who can accept reprimands.
The Bulldogs' win over Collingwood was a spiteful match that featured five charges.
Collingwood's Britt Bonnici and Bulldogs opponent Emma Kearney were charged with misconduct against each other, while Bulldogs player Kirsten McLeod was cited for tripping.
Adelaide duo Deni Varnhagen (forceful front-on contact) and Eloise Jones (rough conduct) were the other players charged.
Collingwood have only one win after five rounds and are a game clear at the bottom of the ladder.
