Josh Walker has triggered a one-year extension with North Melbourne, keeping him at the club until at least the end of 2021.

After joining North as a delisted free agent, Walker has become a key member of the Kangaroos’ line-up, playing every game so far this year. 

Walker has mainly been deployed in defence alongside Robbie Tarrant, but his versatility has seen him move forward on occasion. 

The 27-year-old’s marking ability has been on show this year, and he’s taken the most contested marks of any key defender in the AFL, and the eighth most overall. Walker also leads the Roos for intercept marks. 

It’s set to be an extra special weekend for Walker, who is set to play his 100^th AFL game against Port Adelaide. 

Selected by Geelong with pick 23 in the 2010 Rookie Draft, Walker played 33 games for the Cats before moving the Brisbane Lions. 

He became a key figure at the Lions, playing 52 games, before being delisted at the end of 2019 to the surprise of many, but to the delight of Roos fans.
