CARLTON veteran Kade Simpson will hang up the boots after Saturday night's clash against Brisbane. 

The 36-year-old will finish his career with 342 games across 18 seasons and leaves the club as one of its most decorated servants.

Simpson spent three years as the vice-captain and sits behind only Bruce Doull and Craig Bradley in the all-time games played standings for Carlton. 

"I never believed when I was drafted that I’d still be playing 18 years later," Simpson told Carlton's website. 

"It’s something that hopefully down the track I’ll look back on and appreciate but right now I just want to thank everyone who has helped me, on and off the field, during my career.

"Also thank you to my wife Diana and my family. The support I have received from you has never wavered. You have helped me through the toughest challenges and it has been great to share all the good times with you.

"It has been an honour to play for the Carlton Football Club. This place has been my home for such a long time and I’ve never taken for granted what it has meant to run out in that No.6 in front of what is the most passionate supporter base in the AFL. 

"Thank you to all our members and supporters - the noise and passion you’ve shown at our games is among my greatest memories."

Simpson's former teammate and now coach David Teague also reflected on the journey the skilful defender has forged in his time in the navy blue.

"Many have come and gone from the Carlton Football Club over the last 18 years but Simmo has been our one constant who has never failed to represent our guernsey with class," Teague said.

"You look at Simmo’s build when he walked through the doors in 2002, nobody would have believed that guy would go on to play the third most games in the history of our football club.

"What we didn’t know then was the size of Simmo’s heart, his absolute, never-say-die commitment to get the job done for his teammates, his coaches and our members and supporters.

"He has given everything he possibly can to Carlton. This club simply could not have asked for any more from him and for that we will forever be grateful.

"When this season is over, Simmo will rightly take his place amongst the greatest players to ever wear the navy blue guernsey."
