Fremantle's ruck stocks may have the edge in Thursday night's blockbuster against Collingwood with Magpie ruckman Brodie Grundy ruled out from travelling west.

Collingwood Director of Football Neil Balme ruled Grundy out of Thursday’s game against Fremantle, saying the club will "be conservative" with the 21-year-old.

Grundy has been wearing a neck brace for ten days after suffering a neck injury during training before the Magpies round 11 clash with Greater Western Sydney.

Balme says a visit to a specialist tomorrow will provide a more conclusive update on the injury’s progress.

“He’s seeing the surgeon in the next day or so, so hopefully he’ll get rid of that neck brace,” Balme told Collingwood Media’s ‘Blackmores Injury Update’.

“Naturally he won’t play against Fremantle and we’ll see how he goes after that. There’s a reasonable chance he won’t play the week after either.”

A week of rest and recuperation has helped further strengthen an already healthy Collingwood list.

Only five players are unavailable for selection due to injury this week, with Jarryd Blair over his ankle complaint and Corey Gault cleared fit from concussion.

The selection committee will meet on Wednesday to assess the list and pick a side for Thursday’s clash with Fremantle at Domain Stadium.
