NFL Player Contract
Section 9(e)(ii)Forfeiture of Salary
Players and Clubs may not agree upon contract provisions that authorize the Club to obtain a forfeiture of any Salary from a player except to the extent and in the circumstances provided in this Section 9. For the avoidance of doubt, Paragraph 5 Salary already earned may never be forfeited, and other Salary already earned may never be forfeited except as expressly provided herein. The maximum permitted forfeitures described below do not in any way obligate any player or Club to agree to any forfeiture.
Any reference in a Player Contract to the Policy on Anabolic Steroids and Related Substances shall be deemed also to encompass reference to the Policy on Performance-Enhancing Substances and any amendments thereto; any reference in a Player Contract to the Policy and Program for Substances of Abuse shall be deemed also to encompass reference to the Policy and Program on Substances of Abuse and any amendments thereto.
