Collingwood's Brody Mihocek is in doubt to line-up for Monday's Queen's Birthday clash against Melbourne with injury, while another Pie is set to return.
Mihocek copped a knock to his knee in Round 12's tense four point win over Hawthorn and didn't train with the main group on Thursday, with Pies coach Craig McRae admitting the 29-year-old was dealing with bone bruising in his knee.
"There is a slight concern around him," McRae told media on Thursday.
"He is not going to train much this week. He has got a bit of bone bruising. He hurt his knee halfway through the third quarter. We will have to manage him; he won't train much."
Mihocek is not expected to train much before Monday, but in good news, the forward has been cleared of any structural damage.
Injury plagued forward Jamie Elliot has been confirmed as a return to the side after a bout of illness left him on the sidelines in Round 12, but has recovered enough to rejoin training.
Elliot looks like the choice to replace Reef McInnes, who will be facing a stint on the sidelines as he heads into surgery later in the week.
The 19-year-old will undergo a shoulder reconstruction after suffering a season-ending injury during Sunday's clash.
Collingwood head into the clash as underdogs against the reigning premiers, who have lost their last two games, but McRae is ready to face a tough opposition after a week embroiled in off-field incidents.
"We just worry about getting our own backyard in order, to be honest. It's not something we'll talk about," McRae said.
"I must admit, we focus on what we're doing and trying to prepare ourselves the best we can. We understand they are clearly the best team in the competition for the last 18 months, so we will have to bring our best."
