I saw one in person! Colts @ Titans 2006.

Just looked into it for this comment and it turns out they didn’t actually throw a flag, and this has got to be the definition of this penalty. https://youtu.be/OYCOAvoXLQo?si=wokYSsLr2aAgSx0s&t=364

I was a Colts (read Peyton) fan but I had a Young Jersey on underneath my Colts jacket which I took off after the Titans’ game winning FG
