Collingwood will be forced to make at least one change for Friday night's blockbuster clash against Brisbane at the Gabba.

Players will have the opportunity to put forward their case during Wednesday's main training session. 

Levi Greenwood
Needs to get through training on Wednesday to declare himself fit for selection. GM of Football, Geoff Walsh was confident the hard midfielder would become available for selection on Friday night.

Max Lynch
Best-on-ground in the most recent scratch match against Melbourne. His time will come. 

Rupert Wills
Another solid performance in the reserves game. No official statistics to go off, but to the eye he was a clearance and tackle machine.

Matt Scharenberg
Hasn't played AFL since round 8. Mayne replacement?

Nathan Murphy
Knocking on the door the past few weeks with quality run off half-back in the reserves. Murphy was first emergency for the North Melbourne clash. First game since round 23, 2018 could be around the corner. 

Travis Varcoe
Another possible replacement for Mayne.

Ben Reid
Similar to Greenwood, has to get through main training on Wednesday to be available. Positive signs from Geoff Walsh in the round 15 injury report.
