Carlton veteran Kade Simpson has today announced his retirement from the game at season's end.

One of the modern day greats, the 36-year old calls time on his career after 341 games to date over 18 seasons.

Simpson will finish with 342 AFL appearances to sit third on Carlton's all-time games played list, trailing only Bruce Doull and Craig Bradley.

Taken with Pick 45 in the 2002 AFL Draft, Simpson has forged a career as one of the most durable and reliable statesman and will be long remembered by fans for his iconic long sleeve guernsey.

He played 158 consecutive games from 2005 to 2012, a Carlton record and the third-longest streak in VFL/AFL history.

Simpson won Carlton's best and fairest in 2013 and vice-captained the club in 2013, 2014 and 2016.

The defender thanked the Blues and game at large for everything it has given him.

โ€œI never believed when I was drafted that Iโ€™d still be playing 18 years later,โ€ Simpson told carltonfc.com.au.

โ€œItโ€™s something that hopefully down the track Iโ€™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.

โ€œThe bond you have with your teammates is why you play footy so thank you to all the boys Iโ€™ve shared the field with. My coaches and all the staff who Iโ€™ve worked alongside, there is no way Iโ€™d still be running around without your help.

โ€œAlso 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.

โ€œIt has been an honour to play for the Carlton Football Club. This place has been my home for such a long time and Iโ€™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 supportersโ€”the noise and passion youโ€™ve shown at our games is among my greatest memories."

Blues coach David Teague was full of praise for everything Simpson has accomplished.

โ€œMany 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,โ€ Teague said.

โ€œYou look at Simmoโ€™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 didnโ€™t know then was the size of Simmoโ€™s heart, his absolute, never-say-die commitment to get the job done for his teammates, his coaches and our members and supporters.

โ€œHe 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 greatful. When this season is over, Simmo will rightly take his place amongst the greatest players to ever wear the navy blue guernsey.โ€
