Collingwood defender Jack Madgen is set to be sidelined for six weeks due to a dislocated shoulder, while skipper Scott Pendlebury and forward Jack Ginnivan appear to be over the respective illnesses that forced them out of last Friday's clash with the Western Bulldogs.

Madgen joins a Magpies casualty ward that includes Brodie Grundy, Nathan Kreuger, Jamie Elliott, Jordan Roughead, Charlie Dean and Will Kelly.

Meanwhile, according to Fox's Drew Jones, Pendlebury and Ginnivan trained on Tuesday and look set to be available for selection on Thursday night, while Elliott is nearing a return to action after suffering an AC joint injury in Round 4 against West Coast.

However, further reports from Sam Phillips of 9News have claimed that veteran Steele Sidebottom was the latest Pie struck down by illness and failed to take part in the club's latest session.

Collingwood will be hoping to right the ship this week when it faces Fremantle in Perth on Sunday evening.
