"We’re excited to welcome Jake Kelly to the Essendon Football Club," Dons list manager Adrian Dodoro said.

"We know Jake brings important experience and will work really well alongside the likes of Jordan Ridley, Nick Hind, Jayden Laverde, Mason Redman and Dyson Heppell in our new-look backline. He is a seamless fit with his ability to play on dangerous small to medium forwards, so we’re really pleased Jake has chosen to come to Essendon.

"In our discussions with Jake, he is very excited and motivated by the direction the club is headed, and we look forward to seeing what he can contribute to our emerging playing group in years to come."
