The former Launceston talent was drafted with pick nine in last year's national draft and has averaged nearly 10 touches a game across six matches.

The 19-year-old said he had been thrilled to sign a new contract.

"It's still a bit surreal being on an AFL list, but the whole experience has been a dream come true since day one," Jones told the Adelaide website.

"Every single person at the club has been awesome to me, all of my teammates and coaches. I can't wait to continue to learn from all of them over the next few years and strive to get the absolute best out of myself."

After polling 12 votes from seven games to finish third in last season's TSL player of the year award, Jones made his AFL debut in a round one loss to Hawthorn.

The former Kings Meadows High student slotted a goal with his first kick in AFL football and played the first four rounds before returning for tight losses in rounds nine and 10.

Crows general manager Justin Reid said Jones had made a promising start to his AFL career.

"Chayce has impressed everyone at the club since he arrived with his talent, strong work ethic and overall character," Reid said.

"We obviously rate Chayce highly and are excited to see him continue to develop.

"Chayce has a very bright future ahead of him and will play a huge part in helping to take our club forward."
