DONE DEAL: Dunn moves to Collingwood, Williams to North Melbourne

Melbourne defender Lynden Dunn has made the move to Collingwood, as both clubs have exchanged third round picks.

The Magpies sent pick 47 to Melbourne in exchange for Dunn and pick 51, as the Pies get the player they wanted.

Dunn played just four times for the Demons in 2016, but has made 165 appearances in the red and blue of Melbourne since making his debut in 2006.

The 29-year-old averaged 14.5 disposals and 4.4 marks a game over the course of his 10-year career.

Minutes after securing the Dunn deal, the Pies let defender Marley Williams move to North Melbourne for pick 105.

The 23-year-old played 11 times for Collingwood this season, and made 68 appearances for the Magpies since 2012.
