GEELONG midfielder Mitch Duncan has signed a two-year contract extension, which will see him remain a Cat until the end of 2020.

Duncan, 25, said he was excited to secure his future after seven seasons at the club. 

"The Geelong Football Club gifted me the opportunity to play AFL football and I couldn’t have asked for a better experience so far," Duncan said. 

"To play in a premiership and alongside some of the greats of the game over the past seven years has been a dream come true. I’m really excited to have signed on and I’m looking forward to what we can achieve in the future." 

Geelong general manager of football Steve Hocking said Duncan was an instrumental leader at the club. 

"Mitch is an integral part of our future so we’re pleased to have secured him until the end of 2020," Hocking said. 

"He’s a leader of the club and displays the values we aspire to live by. Mitch has been a great contributor to the club over his seven seasons and we are confident he will continue to do so over the coming years." 

Duncan was selected at pick 28 in the 2009 NAB AFL Draft from East Perth and was a member of the Cats’ 2011 flag side.
