You might be wondering why the Jaguars and Cowboys are wearing red patches on their jerseys and red stickers on their helmets during today's game in London. Allow us to explain!

Those little red things are called remembrance poppies, and they are traditionally worn by people observing Remembrance Day, a holiday observed on November 11 (like Veterans Day in America) by the Commonwealth of Nations in honor of soldiers who have died at war. The poppies became an emblem associated with the holiday thanks to the war poem "In Flanders Fields."
