Collingwood captain Scott Pendlebury will not face the Crows at the MCG this weekend after undergoing a second round of surgery on his broken finger.
Forward Darcy Moore and midfielder Travis Varcoe will also both miss Sunday's clash, after the pair failed to finish Collingwood's win over the Eagles last weekend.
Pendlebury missed Sunday's win after breaking his finger against the Suns the week before, and is now in doubt to play again this season after a complication that required additional surgery.
โWe thought Scott was progressing well after his initial operation but one of the small fractures that he had in the finger became detached from one of the pins that were in the top joint,โ General Manager of Football Geoff Walsh told collingwoodfc.com.au.
โUnfortunately, that meant he had to have some surgery on Monday to put that little piece of fracture back in place.
โThatโs a further complication and now weโre looking at multiple weeks for Scott.
โHe could be back before the end of the year, depending on his recovery time, but we have a few weeks ahead of us before we can give you any certainty on that. It is a setback we didnโt anticipate.โ
Moore suffered a neck injury and Varcoe dislocated his elbow and was concussed after a heavy landing against West Coast, although Walsh confirmed the duo should only miss one match each.
โThe good thing is there are no structural issues,โ Walsh said.
โHe is a pretty sore boy. He got a direct whack, which was pretty severe to the back of the head.
โI would suspect, given the severity of the knock, that he would miss this week but other than that, we should be looking at a return to play soon after that.
โTravis has some reasonably good news, too. The elbow was dislocated and he did suffer a concussion as well, but the dislocation put back in quite quickly and without too much structural damage.
โHe is a very sore boy and there is a significant amount of bruising around the elbow joint.
โThe best-case scenario is that he may only miss this week and then be up and about.
โItโs certainly not a season-ending injury.โ
