Delisted Lion Josh Walker is on North Melbourne’s radar, according to a report in the Herald Sun.

The Kangaroos will be missing a key cog in their backline after the retirement of Scott Thompson, and it is believed that they see Walker as someone who can fill that void.

North coach Rhyce Shaw has just Robbie Tarrant and Majak Daw at his disposal as the club’s only experienced defenders, with the latter not playing at AFL level in 2019.

Shaw has made no secret of his desire to sign a tall back and after missing out on former Port Adelaide defender Dougal Howard, he could make a push to sign Walker.

Walker, 26, was surprisingly cut by the Lions two weeks ago after four years and 52 games with the Queensland club. He managed nine of the first 10 matches in 2019, but only managed another two matches as he was squeezed out as the Lions surged up the ladder.

He has played a total of 85 games after 33 with Geelong between 2012 and 2015 where he was mainly used as a forward.

North Melbourne can sign Walker as a delisted free agent while the window is open until November 11. There are two other delisted free agency windows in November (13th to 22nd and 29th).
