North Melbourne have officially signed Tom Lynch as a pre-season supplementary selection, completing the Kangaroos' list for the 2022 season.

The 31-year-old played 164 games over 12 seasons for the Adelaide Crows and St Kilda before taking up an opportunity with the Kangaroos.

Lynch arrived at Arden Street at the beginning of November and has been working under David Noble as a development coach across the pre-season with a focus on mentoring the club's young forwards.

"This signing leaves the door open to Tom playing state level football in the VFL," North Melbourne’s General Manager Football Talent Brady Rawlings said.

"He will add depth and experience to our VFL side and will play a key role in developing young forwards in Charlie Comben, Jacob Edwards, Phoenix Spicer among others."

"Tom's football resume speaks for itself. His experience after more than a decade in the game is an asset for us as both as coach and a player."
