Retired Essendon veteran Tom Bellchambers is set to return to Tullamarine as the Bombers' ruck coach for the 2021 season.

The 31-year-old announced his retirement from the game earlier this year, ending his time in the AFL after 136 games in the red sash.

Bellchambers is understood to have played a major role in young ruckman Sam Draper's development in 2020, and will look to help Andrew Phillips and new recruit Peter Wright ahead of next season.

Bellchambers expressed his delight to remain with the Bombers.

"I'm very happy and grateful to be back working with the club I love," Bellchambers said, per the club website.

"I'm excited to work with Sam (Draper), Nick (Bryan), Andrew (Phillips) and newcomer Peter Wright.

"The improvement I saw from Draper last year was another factor in wanting to help continue what we started in the hub.

"I look forward to the opportunity to develop the younger brigade and think I have a lot to offer in this area."

Essendon coach Ben Rutten was thrilled to add Bellchambers' experience to his coaching box.

"To have someone of Tom's experience and his knowledge of the game to mentor and support our emerging ruckmen is a wonderful fit for our football program," Rutten said.

"Tom has been a terrific servant of our football club and returning so soon after his retirement to support our young players just highlights his loyal commitment to the red and black."
