PAUL Chapman will play his last AFL game this Saturday night against Richmond after confirming his retirement.

The Essendon forward and former Geelong star has battled injury in his second season with the Bombers, managing just eight games so far.

It was expected the 33-year-old would call time on his career at the end of this season, with teammates Dustin Fletcher and Jason Winderlich also likely to hang up the boots.

The three-time Geelong premiership player and Norm Smith medallist said he found it difficult telling his Essendon teammates of his decision on Tuesday, but knows it is the right time to bow out.

"I know what I'm leaving behind and not being able to come in here and see these guys, 40 of your mates, it's tough," Chapman said.

"I've got one more game to go out and have some fun and hopefully have a win with these guys.

Chapman played 251 games for the Cats, and starred in their 2007, 2009 and 2011 premierships.

He was judged best afield in their Grand Final win over St Kilda in 2009, when he gathered 26 disposals and kicked three goals.

The Bombers recruited him at the end of 2013, when his contract was not renewed by the Cats, and he kicked 22 goals in 20 games with the club last year.

He has spent some time at VFL level this season and had injury concerns, and feels ready to step away from the game.

"It's been heaps of fun over 16 years, it's been hard work but it's time to move on," Chapman said.

"Maybe coaching or something like that might be in the works. 

"I'm not really sure as yet. If I could stay in footy in some capacity that would be great."

Geelong coach Chris Scott paid tribute to Chapman for his efforts in blue and white.

"Chappy will go down as a legend of the Geelong Football Club," Scott said.

"He was a privilege to coach and his contribution to our football club will never be forgotten. Paul's playing record speaks for itself, but it doesn't show the fierce competitor and the determination that he displayed in every game he played.

"His contribution is much more than the statistics and awards. You only had to watch the intensity he brings to know how much football means to him."
