Harry Morrison will wear the No.1 on his back next year in honour of his late godfather and former Hawthorn premiership player and coach Ken Judge.
Judge, who also played for Brisbane and coached West Coast, died almost three years ago on his 58th birthday after a long battle with cancer.
"As a club, we felt fans and members alike were ready to see the No.1 back out on the field," Hawks football boss Graham Wright said.
"Harry is a promising young player and a great clubman, and he's humbled to get the opportunity to share his godfather's jumper number."
