Geelong skipper Joel Selwood will run through the banner with Levi Ablett, son of Cats legend Gary Ablett Jnr, before making his record-breaking and potentially final appearance in the AFL grand final.
Selwood, who is yet to confirm whether he will play on next year, will surpass Hawthorn legend Michael Tuck's league record when he leads the Cats out for his 40th final in Saturday's decider against Sydney.
Ablett, Selwood's premiership teammate in 2009 and 2011, retired after Geelong's 2020 grand final loss in Brisbane but wasn't able to carry his son, who has a rare degenerative disease, on to the field.
"It's an important day. Levi Ablett will be running out with me tomorrow," Selwood told reporters on Friday.
"When Gary went out of the game, it was pretty hard.
"We were up north and our fans probably haven't got to thank him and the family enough.
"So we thought it was just a little kind gesture we could send their way."
Selwood has played 354 games for the Cats since his 2007 debut and has played finals every season except 2015, with a 21-18 finals record.
When asked whether he would retire if he won a fourth premiership, and his first as captain, Selwood, 34, quickly attempted to move on.
"Another one trying to push me out the door. But that's OK," he said.
"I just feel so lucky that I have been able to be in (good) a side along the journey.
"Forty finals, that's probably crept up even on me. But right from the outset, I've played among a lot of good players.
"I play every game like it will be my last and this one will just be the same.
"We'll have those discussions, and we'll be aligned as a footy club whatever that [decision is]. But there's no resting yet, I've got to make sure that I've got a job to do."
