Sydney's Tom McCartin will miss their elimination final through suspension unless the Swans successfully challenge his ban at the AFL tribunal.
McCartin's season might be over after his high bump on Adelaide's Shane McAdam earned him a two-game ban for rough conduct.
The Swans defender and McAdam were going for the ball in the frenetic last term of Saturday night's controversial one-point Sydney win when they collided.
McAdam was laid out in the incident, which was graded careless, high impact and high contact.
Collingwood will also weigh up whether to take Beau McCreery's one-game ban to the tribunal.
McCreery is currently sidelined for Friday night's match against Essendon after he was suspended for a dangerous tackle on Brisbane's Darcy Wilmot.
If the suspension stands, McCreery would return for the Magpies' qualifying final.
Geelong veteran Mitch Duncan joins McCreery as the latest players punished under the AFL's season-long crackdown on dangerous tackles.
With the reigning premiers out of finals contention, Duncan's season is over after he was suspended for one game over his sling tackle on Jack Higgins.
