The NFL says it will team up with the Royal British Legion to mark Remembrance Sunday on Nov. 9.
The Jaguars are the "home" team that day for the third regular-season NFL game in London this year.
In line with the legion's poppy charity appeal, the uniforms and helmets of both teams will feature the red poppy logo. At the end of the game, 80,000 poppies will be dropped into the Wembley stands. The uniforms will be auctioned off for charity.
Poppies are traditionally worn to commemorate the sacrifice of those who died for Britain.
Money raised by the poppy appeal goes to support current and former members of the armed forces and their families.
