Collingwood dynamo Jordan De Goey won't face Fremantle and could potentially be sidelined for longer after suffering an abdominal strain in the Magpies' dramatic win over Adelaide.
De Goey, 28, left Tuesday's training early after failing to get through the session and will go for scans to determine the severity of his injury.
He returned from two weeks out with a groin injury against the Crows and despite feeling the abdominal issue in the third quarter, played on to ultimately kick the winning goal on Saturday.
"Jordy won't play," coach Craig McRae said.
"He's got a fresh injury, he's got an abdominal strain. He got that in the game and played through it and pulled up quite sore from it. He's getting scans now to check out what that means.
"We tried to give it some time just to see how it was going and he obviously didn't get through it (training) and then went off for scans. We'll find out a bit more how deep it it is."
De Goey's loads were scaled back in recent weeks over concerns he could develop the debilitating groin issue osteitis pubis (OP).
He experienced groin soreness after the Adelaide game but McRae dismissed any concerns over the previous injury.
"No, this is a separate injury," he said.
"Actually the other one has sort of settled down and this has expressed itself as an abdominal injury.
"It's nothing to do with OP. We actually worked through that process of assessing it wasn't OP or the start of that."
McRae indicated the Magpies would "reshuffle" to cover De Goey's absence in midfield.
Forwards Beau McCreery and Brody Mihocek are on track to return from concussion and a hamstring strain respectively after training normally on Tuesday.
"Likely that Beau and Brody will play. They got through training," McRae sad.
"That was the plan - you get through, you're more likely to play. So we'll probably pick those two.
"It's (the forward line) been a bit of a revolving door.
"I said after the game (forwards coach) Scott Selwood's done an incredible job because it just hasn't looked the same for three or four weeks now and we're managing to find ways to still score."
Jamie Elliott, Dan McStay, Jeremy Howe, Reef McInnes and Will Hoskin-Elliott are among the attacking options still sidelined.
McRae indicated with a six-day break and a long trip to and from Perth for Friday's game that resting players could be on the cards.
Big man Nathan Kreuger is in the mix to play while West Australian Ed Allan could debut.
Youngster Tew Jiath hobbled off at the end of Tuesday's training.
