Collingwood have run out of patience with back-up ruckman Cameron Wood, including him among five delistings from the AFL club.
Wood only managed six senior games this season for 48 matches with Collingwood and a career total of 64.
The Magpies also delisted defender Simon Buckley, who played 13 games this season for a career total of 47.
Three days after the end of the trade period, Collingwood also cut ruckman Jonathon Ceglar and small forwards Kirk Ugle and Luke Rounds.
Also on Monday, North Melbourne announced they had delisted eight players, including small forwards Matt Campbell and Cruize Garlett.
Wood was a first-round draft choice for Brisbane in 2004 and played 16 games for the Lions before he was traded to the Magpies, again for a first-round pick.
But he could never establish himself in the senior side behind their No.1 ruckman Darren Jolly.
The signs were bad for Wood when Collingwood coaching director Rodney Eade said he "had a bit of a disappointing year."
"He had opportunities and didn't grab them, and his form at times in the seconds was poor," Eade told the AFL website.
"He's got some good attributes, he's good at his craft, a good tap and a beautiful kick.
"He just needs to get that consistency at work rate."
Collingwood have reorganised their ruck backup for Jolly, with Chris Dawes going to Melbourne and Quinten Lynch joining from West Coast.
Buckley played 21 games over three seasons at Melbourne before he joined Collingwood two years ago.
Campbell played 82 games for the Kangaroos after his 2007 debut and the club unsuccessfully tried to trade him in this trade period.
The other players cut from North's primary list were Ben McKinley, Ben Warren and and Ben Speight, plus rookies Malcolm Lynch, Brad Mangan and Gavin Urquhart.
Collingwood director of football, Geoff Walsh, said the delistings were a reality of professional football life.
"All of the boys did what they could to give themselves a chance and they were good people to have around the club," Walsh said.
"People don’t always see what sacrifices are made to try to forge an AFL career. We thank all of them for that effort and wish them well."
The changes mean that, with Quinten Lynch, Clinton Young and Jordan Russell recruited in the recently concluded free agency/trade period, Collingwood will take four live picks – 18, 19, 21 and 39 - into next month’s national draft on the Gold Coast.
