Port Adelaide defender Dan Houston has been whacked with a massive suspension following a front-on bump against Adelaide's Izak Rankine.
Rankine was running with the flight of the ball before being collected by Houston and was stretchered from the field.
The Crows matchwinner was hit high and left concussed, prompting the Match Review Officer (MRO) to step in and sideline the Power defender.
The MRO graded the incident as careless conduct, severe impact and high contact.
Houston will be sent straight to the Tribunal and could miss four weeks of football.
If that were the case, the Power will be without their All-Australian for the entirety of the finals series, unless they make the grand final.
Eight other players received the attention from the MRO, resulting in a hefty fine pool, totalling to $30,000.
Giants defender Lachie Ash also copped a one-match ban for his dangerous tackle on Fremantle's Hayden Young.
The MRO saw the incident as careless conduct, medium impact and high contact.
Ash also copped a fine for staging and was offered a $1,875 fine ($1,250 early plea).
Melbourne pair Jack Viney (rough conduct) and Jacob van Rooyen (striking) also received financial penalties as well as Collingwood's Patrick Lipinski (tripping), Geelong's Max Holmes (umpire contact) and St Kilda's Hunter Clark (umpire contact).
