Robertson has become a pin-up boy at Brisbane after his jumper was ripped from his body amid a fiery contest with the Magpies, with the 22-year-old deciding to continue in the match topless for some time before being handed a new jumper.
The incident saw Robertson's follower count on Instagram grow from 11,000 followers to as many as 15,000 by the end of the match, with his follower count currently set at 71,700.
Robertson made light of the situation last week via a post on Instagram.
The young Lions midfielder is now auctioning off the ripped guernsey from his Round 23 performance, with the club revealing on Tuesday that fans can bid for the jumper for a good cause.
The initial bid was set at $1,000 and the price has since doubled, with bids coming in ahead of the Wednesday night deadline.
The money raised will go to the BCNA - a charity chosen by Robertson and one that is close to the club.
The mother of Robertson's teammate Jarrod Berry and ex-Lion Tom Berry, Jedda, lost her battle with breast cancer a decade ago.
"He asked if we'd auction it off and donate the money, so it's pretty special by Dev," Berry said, via AFL.com.au. "It's 10 years since mum passed.
"It's not so much about the money this year, it's more about her legacy she left with us three boys and our two best mates … we want to bring the community together and celebrate some of the life lessons she taught us.
Both Jarrod and Tom Berry, as well as brother Joel and some friends, will run a marathon to their hometown of Horsham in Victoria's west in November to further support the cause.
