Geelong defender Tom Stewart has signed a three-year extension with the Cats, with the 27-year-old set to remain at Kardinia Park until the end of the 2024 season.

The two-time All-Australian joins Rhys Stanley, Zach Tuohy and Brandan Parfitt in signing new deals with the Cats this week.

Stewart has played 86 games in just four seasons with Geelong, rising to be one of the league's mosttom elite defenders.

The Barwon local is a clean user of the ball and a strong contender in the air and is also an assistant coach with Geelong's AFLW side.

The Cats are understood to be close to announcing new deals for Tom Hawkins, Lachie Henderson and Sam Simpson, while Stefan Okunbor is set to stay on as a Category B rookie.

Brad Close, Zach Guthrie, Quinton Narkle, Ben Jarvis, Jake Tarca and Darcy Fort are yet to sign a contract for 2021.
