Carlton young gun Tom De Koning has penned a new deal with the Blues that will keep him at the club until the end of the 2023 season.

The two-year extension comes after a breakout season with the Blues, playing both ruck and forward under David Teague.

De Koning impressed against some of the league's best talls in 2020, showing off his strong athleticism and ability in the air.

The 21-year-old played seven of the Blues' last eight games of the season and has cemented his place in Teague's side.

De Koning joined the Blues via the 2017 draft, taken with the 30th overall selection.

Carlton list manager Nick Austin was pleased with the singing and acknowledged De Koning's work-rate.

“Tom has a lot of talent but what we love is his commitment to make the most out of that talent through his workrate and dedication to becoming the best ruckman he can be for the Carlton Football Club,” Austin said.

“He has completed the perfect apprenticeship under Matthew Kreuzer and we have full confidence that Tom is ready to take the next step in his career. We believe Tom not only has the ability but the determination to be a great player for our football club for a long time to come.

“On the back of already having 13 players re-sign since the season ended, to also have Tom keen to sign a two-year extension despite still having another year to run on his current deal, is another sign of the strong belief our playing group has in the direction we are heading.”
