As the NFL contemplates the question of whether and to what extent the players deemed to have harassed Dolphins tackle Jonathan Martin should be punished, the league has a potentially major problem when it comes to Dolphins guard Richie Incognito.

The Collective Bargaining Agreement states that only one penalty may be imposed on a player.

Article 46, Section 4 — titled “One Penalty” — says that there shall be only (duh) one penalty: “The Commissioner and a Club will not both discipline a player for the same act or conduct. The Commissioner’s disciplinary action will preclude or supersede disciplinary action by any Club for the same act or conduct.”

Per a league source, the NFLPA intends to fight any discipline of Incognito based on Article 46, Section 4. The potential battleground comes from the question of whether the league would be disciplining Incognito for the “same act or conduct.”
