The poppy shirts worn in the Sheffield derby last month are going under the hammer as part of the Sky Bet Poppy Auction.
The auction of signed memorabilia from across the EFL's 72-member clubs is raising money for The Royal British Legion's Poppy Appeal.
17 Blades shirts, all emblazoned with the special poppy and gold 'Sheffield Remembers' writing on and signed on the front and back by each individual player, are being auctioned on the CharityStars website.

Sky Bet's relationship with the British Legion now spans five seasons, with over £350,000 raised, thanks the help of fans and clubs throughout the EFL.
The Royal British Legion's Ben France said: "As the Centenary of the First World War comes to a close, The Royal British Legion is asking the nation to say Thank You to the First World War generation, who served, sacrificed and changed our world forever. That's not just the British Armed Forces, but those who fought alongside from all corners of the world, and the men, women and children who played their part and suffered hardships at home.
"With the auction of the 2018 poppy shirts, we're hugely grateful for the continuing support of our partners Sky Bet and the clubs of the English Football League. Through the incredible generosity of the fans, we will ensure today's Armed Forces and their families receive the support they need, and their unique contribution is never forgotten"
Meanwhile, Mark Duffy's signed shirt from the Sheffield derby will be raffled in the Blades Superstore, with all proceeds going to the Royal British Legion's Poppy Appeal.
