The number one rule about the fight club is to not talk about the fight club, but for some NFL players, it could help reduce suspensions. Mike Florio of Pro Football talk was reviewing the NFL rules on performance-enhancing drugs regarding the  Julian Edelman suspension and discovered that players who turn on other players or trainers after being suspended can get their suspension reduced. Via Pro Football Talk:

“The NFL Management Council may, prior to the conclusion of a Player’s appeal, reduce the length of the suspension and corresponding bonus forfeiture by up to 50% when the Player has provided full and complete assistance (including hearing testimony if required) to the Management Council which results in the finding of an additional violation of the Policy by another Player, coach, trainer or other person subject to this Policy,” the policy states.

There haven't been any reported times where another player turned on a teammate but it's interesting that if a player brings down more players, the suspension will be reduced.

It's hard to imagine a time where a player would turn in another teammate because that would lose all the credibility in the locker room.

It could end up costing said player another contract with the team or get them cut altogether. PED's don't seem to be a huge problem right now in the NFL but it seems a handful of players each year are caught. If people caught took advantage of this rule, the number of suspensions would probably go up.
