No AFL debut for Pies son of a gun Brown

Collingwood father-son pick Callum Brown will have to wait a little longer for his AFL debut, with the rookie forward to miss Sunday's game against Fremantle.

Brown - the son of former Magpies skipper Gavin - was named in a 25-man squad for the Domain Stadium clash but failed to make the final cut.

Jackson Ramsay and Ben Crocker have replaced Jarryd Blair (omitted) and Alex Fasolo, who is battling depression, in the final 22.

Fremantle have swung three changes after copping a 100-point thrashing from Adelaide last week, with Danyle Pearce, Garrick Ibbotson and Jonathon Griffin all dropped.

Ruckman Aaron Sandilands returns from a hamstring complaint alongside Ed Langdon and debutant Luke Ryan.

The 12th-placed Magpies haven't beaten eighth-placed Fremantle in Perth since round 23, 2011.
