Up to six players are in line to break into Collingwood’s team ahead of Sunday’s clash with Port Adelaide.

Mason Cox, James Aish, Tim Broomhead, Callum Brown, Josh Daicos and Josh Smith have all been added to the Magpies’ extended 25-man squad.

The Pies will be without suspended ruckman Brodie Grundy and injured duo Levi Greenwood (knee) and Daniel Wells (quad).

Ruck and roll
Collingwood’s ruck division will be carried by Mason Cox, who last appeared at senior level against Essendon in round 16.

He is averaging 22.7 hitouts in nine VFL games this year, and has enjoyed a purple patch in recent weeks, averaging 34 hitouts and 20 disposals in his past three games.

Cox has also kicked a goal in all bar one of his nine VFL games, with a high of six against Port Melbourne in round 10.

Will we see a debutant?
Josh Daicos remains in contention to make his senior debut before the season is out.

The teenager was named as an emergency against Adelaide a fortnight ago, and has again been added to Sunday’s extended squad.

Daicos is averaging 16.2 disposals in 14 VFL games, to go with his eight goals. He collected a season-high 26 disposals and a goal in last week’s win over Werribee.

Get Wells soon
Collingwood will be without two of its most experienced midfielders this weekend.

Levi Greenwood will sit out the next 2-3 weeks due to his knee complaint, while Daniel Wells’ quad injury will sideline him this weekend.

Brodie Grundy, meanwhile, will not appear until the final round of the year after accepting his two-week suspension.
