The trio have all featured for the Cats this season, with Kolodjashnij cementing his spot in the side over the past 12 months.
After joining the club at the end of the 2014 season, the 22-year-old has played 43 games since debuting in round 12, 2015, and is an important member of Geelong’s back six.
“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 geelongcats.com.au.
“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.”
