Head of List Management James Gallagher said McKernan was a handy acquisition to help cement the club’s ruck and forward structure.

“We’re really pleased to have signed Shaun for next season,” Gallagher said.

“Our structure in the ruck and key forward roles, having Paddy, Max and Rowan all available, was a real cornerstone of our game plan this year.

Shaun will provide us with the depth and flexibility we need to ensure that we are able to maintain that structure across the 2021 season.

“His experience will also be a great asset to assist in the growth of our young list.”

McKernan played 34 matches for Adelaide before moving to Essendon in 2015 to register another 53 games.
