DEFENDER Jake Kolodjashnij leads the list of Geelong players to recommit the club, with the versatile Tasmanian signing on until the end of 2019.
Forward Wylie Buzza and Jordan Cunico have also signed on for the next two seasons after showing promise at AFL level this year.
Kolodjashnij, 22, has played 43 AFL games and has recently pushed away from the backline to spend time on the wing.
He's played 14 games this season after a groin injury delayed his start until round eight.
Buzza has played five AFL games since his debut in round 15 this year, and had 14 disposals and kicked a goal against Collingwood on Saturday after being recalled to the team.
Cunico, a 21-year-old utility, played his first AFL game in round 10 this season after a knee injury ruined his 2016.
"It's really pleasing to re-sign these three young guys at this point of the year, a great boost heading into the end part of the season," Geelong’s general manager of football Steve Hocking told the club's website.
"We see Jake, Wylie and Jordan as key members of our team well into the future.
"Jake has already shown his ability, work ethic and versatility. He plays and prepares in the Geelong way and makes our team and our club better.
"Wylie and Jordan continue to work hard at their craft and while they haven't experienced a lot of football at AFL level, we hope to integrate them as part of our core group in the coming years.
"Both display the values of the club whilst showing great potential for future success."
The Cats have a number of free agents – both restricted and unrestricted – to sort out in the coming months.
Steven Motlop, their only restricted free agent, headlines the list with his future at Geelong still uncertain.
Veteran defender Tom Lonergan is open to playing on but needs a new deal, while Andrew Mackie's intentions for a 16th season remain unknown.
Negotiations between Daniel Menzel and the club are on-going, and he has been public in stating he wants to remain a Cat – and believes he will with an offer understood to be on the table.
But, it is also believed his management has tested the waters with other clubs to gauge interest in the dangerous forward.
