Collingwood will challenge defender Billy Framptonโs one-match ban at the AFL tribunal on Tuesday.
Frampton was cited for rough conduct for an incident with North Melbourneโs Matt Whitlock in the fourth quarter of their clash on Friday night.
Frampton tackled Whitlock to ground near the goal square and the act was assessed as careless conduct, medium impact and high contact which equalled a one-match suspension.
The challenging of Framptonโs ban ahead of Saturday nightโs crunch match against Carlton comes as the Magpies face the prospect of being without a recognised and seasoned key defender unless Frampton is cleared.
Collingwood have brought in mud-season pick Liam Puncher to fill the breach, in the absence of skipper Darcy Moore who is gone for the season.
Frampton has been greatly improved as a tall back and the Pies would not have a suitable opponent for Harry McKay โ Puncher being much less powerful or experienced โ if Frampton remains suspended.
Frampton โs tackle was ruled dangerous when Whitlock was taken from behind and dispossessed, leading a free and advantage call and goal to the Kangaroos.
The tribunal case is due to be heard on Tuesday night.
