The Cobblers players will take to the field against Gillingham on Saturday with the Remembrance Day poppy emblem added to the front of their claret shirts.
After the game the players’ shirts will be auctioned off with via the club’s official ebay site, with all profits donated to the British Legion’s Poppy Appeal.
“I know the club has a long and proud tradition of remembrance,” said chairman Kelvin Thomas.
“The issue of wearing poppies on playing shirts has been in the news a lot lately, and we think it is very important that clubs and players do show their respect.
“We take our role in the community seriously and it is only right that we, as a focal point of the community, remember the sacrifices made by so many.
“The poppy has been added to the playing shirts for the Gillingham game, and we will then auction them via the club’s official eBay site to support the poppy appeal.
“It’s important we pay our respects to those who have laid down their lives serving their country and that we show our support for their families.”
A club statement added: “Links between Northampton Town Football Club and the military are strong.
“Walter Tull might be the name most supporters would recall, but there are thousands of examples of remarkable bravery from so many, including former Cobblers striker Bernard Vann (1887-1918) who was awarded the Victoria Cross, the highest and most prestigious award for gallantry that can be awarded to British forces.”
