Collingwood are again on high alert with two players under illness clouds as they gear up to welcome back Darcy Cameron from injury in the huge AFL clash with Carlton.
No.1 ruckman Cameron, who has not played since round three because of a knee issue, will be named in the final squad for Sunday's MCG contest after getting through training.
But Ash Johnson and Jack Ginnivan both missed Friday's session, told to stay away from the club while sick.
"They've both sort of got the man flu, if you like. Different (levels) of it, we'll have to wait and see," Magpies coach Craig McRae said.
"We've got a principle right now because this time last year everyone got sick, including myself, and I said, 'If you're sick, you're not coming in'.
"We meet them at the door and then send them home, and those two got sent home.
"I'm not sure exactly where that fits. We'll wait in the next 24 hours."
Collingwood have struggled with a ruck personnel crisis for most of the season but are now getting their pieces back together.
Cameron will be picked alongside fellow tall Mason Cox, who was the star of last week's thrashing of GWS.
The pair were the Magpies' first-choice ruck-forward combination in McRae's first season at the helm.
"I'd like to think that we get back to what we had all of last year where there's a balanced approach to it all," McRae said.
"There's respect towards the combination of both but understanding Darcy's been out for a number of weeks.
"I don't think we're there yet but we'd like to be able to work towards that again."
