Collingwood pair Chris Dawes and Alan Didak will have a chance to prove their fitness in Wednesday's main training session.

Dawes (knee) and Didak (calf) both suffered injuries in Saturday night's Semi-Final win over West Coast and are in doubt for Friday's Preliminary Final clash with the Sydney Swans.

The pair took on light duties at Tuesday morning's recovery session at St Kilda Sea Baths with Dawes, wearing a tracksuit, moving very slowly as he took part in handball drills.

Director of Football Geoff Walsh comments on Didak and Dawes' injuries.

Collingwood coach Nathan Buckley was hesitant to go into too many details about the duo's recovery.

"They were very much with us but just on their own individual programs, as are most of our boys. We have a full session tomorrow and we'll see how they pull up," Buckley said.

The Magpies fly to Sydney on Thursday after attending the funeral of former teammate John McCarthy.

Buckley said each member of the team was handling the tragedy in their own way.

"We've encouraged each individual to grieve in his own manner and not feel guilty about whatever they feel," he said.

"There are some guys that didn't know J-Mac at all, who are in this group. They're going to feel bad because the blokes sitting next to them knew him really well and are quite affected by it.

A tribute to John McCarthy.

"On the spectrum from high and low there are plenty of different emotions that the players are going through and we share it together and lean on each other."

Despite the intense emotions that come with such an unexpected tragedy, Buckley said his players could handle the difficult circumstances.

"There's no excuses and despite what the public perception is, every preparation for every game is slightly different in some way, shape or form," he said.

"Whether it's the personnel you go in with, whether it's injury or suspension at different times of the year. We're talking about humans, so they are affected by relationships away from the club as well.

"The fact this is a public circumstance doesn't mean it's any better or worse than circumstances we face at other times. We want to honour a teammate and a mate."
