The popular Pie was drafted pick number 63 in the 2006 draft and went on to enjoy a 165-game career at Collingwood, where he was a premiership player in 2010.
Trouble with injury and form saw him in and out of the Collingwood line-up for the majority of his career, but is a cult hero amongst the Collingwood faithful.
Goldsack was unable to feature in any of Collingwood’s home and away games this year after miraculously coming back from a knee reconstruction last year to feature in all games of the finals series for the Pies.
“I gave it one more year but football’s grim reaper got me,” Goldsack told the players and staff Tuesday morning.
“But I’m content. How could I not be? I realised all of my football dreams, met some outstanding and interesting people and, in a sense, grew up with Collingwood’s arm around me.
“Chelsea and I made the call after the grand final last year to relocate to South Australia in 2020, so we’ve been preparing for the next chapter.
“I hope I did the jumper proud and thank the many, many people who helped me along the way.”
