Looking at the other versions of this card, there are some omitted words and a color variation of the Team NFL shield on your card. I wonder if this is an unlisted Promo card or possibly an error. I have no idea other than it could be the first draft of the card accidently printed and released. And when they decided to release it in a different manner, it got renumbered. Wish I could provide some real information. Sorry
What?? No American Ninja Warrior cards or Ninja Warrior cards yet?? Someone is really slacking!!
