As Baltimore Ravens players left their locker room to face the Denver Broncos this evening, the NBC cameras caught a rare behind-the-scenes occurrence most fans never see (you can watch video courtesy of Deadspin).

NFL officials stood outside of the locker room like TSA agents and randomly began patting down players. Nobody had to take their shoes off, remove a belt, or place liquids in a plastic tray, but the officials were definitely looking for something.

Officials were making sure no player applied anything to their uniform that would make it harder for an opponent to make a tackle. It is actually something that happens before every game, but it grabbed the attention of many people watching at home.

Thanks!

I wonder why they only patted down a couple of the linemen.
