Collingwood will remain without forward Dan McStay for the coming weeks after the club confirmed their forward recruit has suffered an infection in his finger.

McStay has been sidelined since Round 5 due to a ruptured flexor tendon in his finger, with his recovery process expected to reach its cessation through the club's bye period.

In unfortunate news, McStay is battling an infection and is anticipated to miss close to a month of action after the fresh setback was recorded last week.

"Collingwood advises forward Dan McStay has suffered an infection in his finger which was operated on in late April," a club injury update read.

"The 27-year-old initially ruptured the flexor tendon in his finger during the side's Round Five match against St Kilda.

"McStay suffered a setback on the same finger at training last week prior to the Club's Round 13 match against Melbourne.

"McStay will be out for the short term with the Club to provide an update later this week."

While Craig McRae will be without McStay for some time, the Collingwood senior coach could welcome forward pair Jamie Elliott (shoulder) and Jack Ginnivan (managed) for this weekend's clash with Adelaide.

The Magpies will host the Crows at the MCG on Sunday at 1:10pm (AEST).
