Can anyone tell me if there is a rule for NFL players that prohibits them from wearing any type of jewelry or body piercings during a game? I know it is not allowed in the NCAA but what about the NFL?

Rule 5 Section 3 Article 4

In addition to the several prohibited items of equipment and apparel specified in article 3 above, the following are also prohibited:

(a) Metal or other hard objects that project from a player's person or uniform, including from his shoes.

The things referred to in the 'apparel specified' are things like non-approved pants, cleats, jerseys etc.

well, here's what happens...

Provided, however, if the violation involves the competitive aspects of the game (e.g. illegal kicking shoe, an adhesive or slippery substance) player will be suspended immediatley upon discovery.

(c) For repeat violation; disqualification from game

(d) For illegal entry or or return of a player suspended under this section 3: loss of 5 yards from succeeding spot and removal until properly equiped after one down.
