You can now bid for the chance to own a piece of Boro history - special shirts emblazoned with the Marie Curie Cancer Care logo, which were worn for the games against Reading and Derby.
Club shirt sponsor Ramsdens Financial Ltd is auctioning 20 match-worn shirts on eBay over a two-week period - and the bidding has now started!
All money raised from the bids will be donated to Marie Curie Cancer Care, The Football League's Official Charity Partner for the 2010/11 season. The money will help the charity provide more free care to local people in their own homes.
All auctions are for just three days. To bid for the shirts below, just click on the links...
Football League clubs around the country will be dedicating matches and organising collections for the charity between March 7 and 14.
Thanks to the generosity of the UK's largest independent pawnbroker, supporters at Boro's game at Reading on Saturday saw the shirts for the first time and fans at the Riverside for the game with Derby will see the Marie Curie daffodil logo splashed across the shirt instead of the familiar green of the Ramsdens' name.
And it is these limited edition shirts, signed by the players, which eBay bidders can try to win. Not all the shirts will be on sale from the first day of the auction, so fans will have to keep checking the site for the one worn by their favourite player.
Ramsdens Chief Executive Officer Peter Kenyon said the company wanted to make their three-year Boro sponsorship work for the wider community as well as for both the business and the club.
"Ramsdens is becoming an integral part of the high streets and communities in which we operate," he said. "We are a 21st Century pawnbroker and have a wide range of services on offer.
"We are very keen to extend our links to the local communities and are delighted to be able to help promote Marie Curie in this way and do all we can to raise funds for the charity."
Manager Tony Mowbray added: "Cancer is something that has touched my life and I think it's a fabulous gesture by Ramsdens to donate their shirt sponsorship to Marie Curie. I hope the fans give the fundraising fantastic support."
Ramsdens is also combining its expertise in phone recycling - one of the many services offered at all its 80 UK branches - to help Marie Curie Cancer Care.
Visitors to MFC's two retail stores, at the stadium and in the town centre, the Ticket Office, main reception and to Ramsdens' nine Teesside shops can drop their old mobile phone into a Marie Curie collection box. The phones will then be sold on for recycling, with money raised being handed over to the charity.
"While the football club connection is giving Marie Curie a superb, high profile, we also wanted to make it possible for non-football fans to donate to the cause," said Mr Kenyon.
"Having shops in the centre of many local communities has enabled us to reach out to a greater number of generous Teessiders.
"Even if they don't have any spare cash to give, they may have an old phone lying in the back of the drawer that they can donate instead. And with the average phone fetching £15, we hope to raise hundreds of pounds this way."
Boro staff are doing their bit to help during Marie Curie Cancer Care's national fundraising week with a cake and coffee sale and a Dress Down Day today.
Middlesbrough FC Chief Operating Officer Neil Bausor said: "We are delighted to throw our weight behind Ramsdens' fantastic fundraising efforts and hope that efforts by our club staff will further boost funds for Marie Curie."
