Collingwood star Jordan De Goey could miss the rest of the season after his leg injury appears to be more serious than originally estimated.

Magpies coach Nathan Buckley revealed last week that the 22-year old would miss at least two weeks with "bone stress", but now there is a growing concern that he could be sidelined for longer.

"(Bone stress is) very variable, it's hard to put a timeframe on it," AFLW's head physiotherapist Kathleen Petty said on AFL Gameday on Sunday.

She later mentioned that missing four weeks would be a best case scenario, but "it could push out to six".

Bombers great Tim Watson casted further doubt that the emerging Magpie will be ready in time for finals.

“I don’t know what you’re hearing about Jordan De Goey, but it seems to me that it’s very optimistic that he’ll be back in a couple of weeks,” Watson told SEN Breakfast.

“I was told it was very, very similar to Nathan Fyfe’s, where it started out as a hairline and it may be a crack now.

“If that’s the case, it may be very doubtful that we’ll see him again this year.”

Former Melbourne skipper Garry Lyon thinks De Goey's injury, adding to a growing casualty list at the Holden Centre could catch up the club at some point.

“Collingwood has been great at covering their injury losses, they're fighting a really good fight, but I wonder at some stage whether it's going to hit them hard,” Lyon told SEN Brekfast.

In what was a horror weekend for the Pies on the injury front, high-flyer Jeremy Howe suffered a concussion against Richmond and could miss this Saturday's game against Sydney.

Swingman Brody Mihocek looked proppy against the reigning premiers after hurting his ankle in the early goings.

It appears key defender Matt Scharenberg will be out until late 2019 after suffering a suspected ACL injury in the Tigers clash and forward Jamie Elliott re-injured his troublesome hamstring in the VFL on Sunday.
