Daniel Venables is forced into premature retirement after an AFL medical panel unanimously recommended that he avoid contact sport, including Australian football.
The 22-year-old, who was the youngest member of the 2018 premiership team, has not played since suffering a brain trauma injury in a marking contest in round nine, 2019 against Melbourne at Optus Stadium.
"I'm sad, but I guess I'm relieved because the pressure's off and now I can focus on my rehab. I'm not able to play again, so I can just concentrate on my health," he said.
"It's not until you sit back and reflect on the time that you understand how far you've come and the things you have had to go through. I feel like this has matured me as a person and it will help me in the future."
